    Why didn't they just rename K-9 instead? I just gave it a try and it really is just K-9 with slight UI tweaks.
    • kevincox 8 days ago |
      They did rename K-9. They just also have been making lots of improvements to K-9.

      They still have two different apps, Thunderbird Mobile and K-9, but the only difference is the branding. All of the UI tweaks other than the icons and colours are in both apps. The functionality is identical. So other than not deleting K-9 it is a rename (I guess it is a hard link, not a rename).

        >> making lots of improvements to K-9

        Such as...?

    • prmoustache 8 days ago |
      That is just one of the downsides of the "stores" and basic package managers which do not have dependencies management where you can't do a transitional package.
      • tslocum 8 days ago |
        Why is a transitional package necessary? Surely all of this isn't just to change the package name, which 99% of users won't see or care about.
        • prmoustache 6 days ago |
          I believe it is. Current k9mail and thunderbird are the exact same codebase and exact same dev team.
  • crossroadsguy 8 days ago |
    I believe they will be deleting K-9 from play store after giving its users adequate warming and informing them assuaging them. It's just K-9 right now named Thunderbird. I hope they bring in some important Thunderbird desktop features to mobile as well. The release is underwhelming if not downright disappointing.
    • dugite-code 8 days ago |
      They have stated in the past that K-9 will stick around with just the Icon, name and colour scheme differing.
    • forbiddenlake 8 days ago |
      Why do you believe that?
  • NoboruWataya 8 days ago |
    I've been happy with FairEmail but I think I will give this a try when it hits F-Droid. At this stage it's mainly curiosity, but if they get new features like sync with desktop down the line it will be great.
    • figmert 8 days ago |
      I tried it not long ago. It's nowhere near as polished and good as FairEmail, unfortunately. I didn't last more than a week. There was a lot missing.
      • aquariusDue 8 days ago |
        Yeah, FairEmail is great. Personally I can't sing its praises enough. I'm thinking of upgrading to Pro for the home screen widgets too.

        I also find it surprisingly user friendly, the UI is easy to navigate and the advanced stuff is pretty well communicated e.g. templates and mailbox rules.

    • metasaval 8 days ago |
      I've kept TB Beta installed but still go back to FairEmail. But I'm not an email power user, I really only stick to it because the widgets are better. No dark mode for the K9/TB widget is a dealbreaker. And even then FairEmail goes beyond that in allowing transparent widgets.

      Will keep checking back in over time.

    • red_trumpet 8 days ago |
      K-9 Mail is on F-Droid, if you want to give it a try.
  • gaiagraphia 8 days ago |
    Is there a reason why Mozilla haven't used their position and funding to just hoover up all the most successful open source projects to create a more cohesive ecosystem?

    Surely any addons - like uBlock Origin - which have massive usage should just be baked in to the browser by this point?

    The likes of Nextcloud and Mattermost would also be great additions in trying to create a true rival to Microsoft and Google's offerings.

    Gives open source projects funding and development, Mozilla gets new avenues for subscription money to try and be more independent, and MS/Google's market shares can be chipped away at. Win win win. Potential anti-trust bait when Google start crying and withdrawing funding, too.

      Why would Youtube, which makes money off ads, allow a web browser that blocks ads to access Youtube when they could just refuse to serve their user agent?
      • worble 8 days ago |
        They currently allow Brave which does that.

        If a major website starting blocking user agents for any reason other than compatibility then all that would do is trigger (finally) the deprecation of user agents strings as browsers would all just pretend to be each other.

        • ssl-3 8 days ago |
          It would just be yet another zero-sum meta-war, with web browsers ultimately using randomized user agent strings just as mobiles randomize MAC addresses.

          But none of that means that the war somehow can't or won't occur.

        • AlienRobot 7 days ago |
          Brave and Vivaldi can probably get away with it because they're just a Chromium re-skin.

          Firefox uses Gecko instead of Webkit. They can't change their user agent string.

      • BizarroLand 8 days ago |
        Because they don't want to get sued for monopolistic practices, I guess. Since the Goo owns Chrome and Youtube, Youtube blocking non-chrome user agents would be actionable.

        Even if they whitelisted Safari, that would still be actionable.

        • carstenhag 8 days ago |
          It's not just YouTube blocking something. It's Google not paying Mozilla millions for keeping Google as default search engine
        • AlienRobot 7 days ago |
          I don't believe a court would tell Google it has to provide a service for free.
          • BizarroLand 7 days ago |
            Any competent lawyer could easily make the argument that that is a false equivalence.

            They're not being forced to provide a service for free, they're not being allowed to ostracize essentially the only browser with any meaningful percentage of users that doesn't use their web engine as that is an anti-competitive and monopolistic practice.

      • terminalbraid 8 days ago |
        User agents are trivially fungible thing in this. That's the nature of the internet and how connections are established. Personal hardware constructs whatever packet that is going out and there's nothing special if that packet comes from a sanctioned or unsanctioned client. There's no way for a provider to distinguish the difference between what created an acceptable packet.

        It's difficult for me to envision how that's rigorously enforceable to prevent something outside of the app (like a browser) to access something ultimately consumed by an API without resorting to (expensive and crackable) digital rights management at the hardware level. You can run down whatever train of thought you want, but ultimately since the client is running on machines controlled by the consumer, it can be cracked, reverse engineered, decapped, or whatever. This has been the end state for every attempt the industry has made to control user behavior. DVD CSS, Bluray, Sony's CD rootkit nonsense, every game console, satellite TV cards, analog cable TV, on and on, all broken.

        I'm confident google/youtube wishes there weren't applications like FreeTube and yt-dlp. The fact of the matter is it's practically impossible to exclude them but still keep their own ecosystem functioning at an acceptable cost and with consumer buy in.

    • timbit42 8 days ago |
      I'd like to see FF and TB combined with LibreOffice and maybe add some other apps like Scribus. I don't know whether their licensing permits this.
    • slightwinder 8 days ago |
      > Is there a reason why Mozilla haven't used their position and funding to just hoover up all the most successful open source projects to create a more cohesive ecosystem?

      How does this support their mission or make them money? They are rich, but also wasteful with their spendings. So anything has to show value for their Mission. And they are having enough projects of their own, just none which are really working well.

      > Surely any addons - like uBlock Origin - which have massive usage should just be baked in to the browser by this point?

      uBlock works fine on its own. It's probably better for them to be independent.

      > The likes of Nextcloud and Mattermost would also be great additions

      Nextcloud and Mattermost have both their own company. Do expect Mozilla to buy them out? Or should they just offer a hosted version with their own branding? What would be the value here?

      > create a true rival to Microsoft and Google's offerings.

      Mozilla has no real income outside of Google paying for a position in their Browser. And the money they have is far too low to compete with those behemoths in that space.

    • NoboruWataya 8 days ago |
      I'm not sure I want that kind of "conglomeration" in the FOSS space. Sure, there can be benefits to having a behemoth with a lot of resources behind it to support FOSS projects. But it also brings with it various problems of incentives and resource allocation. Managing multiple different software projects within one organisation is something a lot of well-run, for-profit companies struggle to do effectively, I don't think Mozilla would be much better at it.

      Also, I personally don't have any issue with Mozilla but a lot of people seem to hate them. I can only imagine all the internet drama that would ensue if they started acquiring projects like LibreOffice and Nextcloud.

    • dboreham 8 days ago |
      > uBlock Origin - which have massive usage

      I'm guessing there are legal risk issues with this. While ad blocking flies under the radar as a mom/pop operation with guerilla marketing the offended parties turn a blind eye. Make it a feature of a "corporate" product, and they'll sue.

      • Zak 8 days ago |
        Brave, Opera, and Vivaldi are all corporate, for-profit browsers with adblockers built in.
      • notpushkin 7 days ago |
        I think it’s more likely that the offended parties would stop financing you. IIRC Mozilla still makes most of its’ profit from Google integration.
    • Macha 8 days ago |
      It hasn't exactly helped Eclipse and Apache stay independent, it's basically just some shared project infrastructure at a time when that's less relevant than it used to be.

      > Surely any addons - like uBlock Origin - which have massive usage should just be baked in to the browser by this point?

      Merely listing ublock origin as a "recommended extension" led to them being fined in China about two years ago. You can't even install it in mainland China right now.

    • openrisk 8 days ago |
      Not sure "acquisition" is the right framing in the open source space but one could certainly think of more partnerships, coordination and/or sharing of various components among the various big players and ecosystems.

      FOSS on mobile is a basket case anyway (the dark side is too strong here) but the decades-long linux desktop story is not too hopeful either.

      Things like deep interoperability, look-and-feel, UI conventions etc could go a long way towards making all those important applications feel like a coherent thing rather than a random patchwork stitched together with tape.

  • nxtbl 8 days ago |
    They are keeping both:

    "Quite a few people seem to love K-9 Mail and have asked us to keep the robot dog around. We believe it should be relatively little effort to build two apps from one code base. The apps would be virtually identical and only differ in app name, app icon, and the color scheme. So our current plan is to keep K-9 Mail around."

    • nixosbestos 8 days ago |
      Isn't that something a single App can do? I have some apps that allow you to change their icon, at least...

      I guess if you have a CI pipeline it's easy to copy/paste or add a Matrix job, but it seems like an odd choice.

      • Timon3 8 days ago |
        Not if you want to keep previous app installations updatable etc. while also having a different app ID.
      • devsda 8 days ago |
        Having two separate apps has additional benefit of acting like insurance against any automated/manual playstore review surprises.
        • RicoElectrico 8 days ago |
          Quite the opposite I think, some braindead bot can count that as spoofing or something.

      Incredibly easy if you figure out how to use Android build variants.

      I'm using and loving Thunderbird for Android.

  • dugite-code 8 days ago |
    With it becoming Thunderbird branded my biggest wish is proper subfolder support. Seeing folders as Archives.2024.invoices.paid rather than a nice collapsable list makes mail management a right pain.

    It's also one of the oldest request on the github https://github.com/thunderbird/thunderbird-android/issues/63...

    • philipwhiuk 7 days ago |
      And it's in the same state I said when I commented on it for the same reason as I commented. A scrolling List View is really easy to implement. A proper infinitely nested folder UI is harder and none of the 'off-the-shelf' things worked at the time.

      (There's a bunch of comments that are just wrong, the code does 'understand' the separators, it just doesn't do much with that knowledge).

      The UI last time I used it used a mixture of web-views and standard components.

      We were at the time handling the Material UI transition to make it look like a modern app.

      Until that was done there was very little incentive to invest a lot of time in a UI that would be scrapped when that happened.

      Other big projects (like the Android timers change which broke reliable email fetch or battery life) were also prioritised ahead of it (for reasonable reasons).

      Honestly with only cketti and another person working on it part-time, the project struggled to do more than (or even) keep pace with the Android ecosystem. Maybe now it can. But the release cadence and approach was painfully slow.

      I stopped my involvement with the project when I switched from Android to Apple - my motivation was always improving my own email experience.

      • dugite-code 6 days ago |
        Hey thanks for the work in the past, you did amazing work. No doubt imaps loosness with how it returns data made it an even more complex task.

        I hope joining Thunderbird is going to pay dividends for big task like this one.

  • jrm4 8 days ago |
    I'll try to do it less snarky than others but;

    This is fine, but frankly we'd love to see resources toward returning Thunderbird to be the more open thing it once was.

    Losing the robust plugin system was incredibly frustrating; like, all I want is the ability to have custom colored accounts back.

    • KetoManx64 8 days ago |
      Custom colored accounts exist in FairMail (Open source as well)

    Is there any way to get push notifications instead of polling? My email provider is Fastmail, maybe there are some kind of IMAP extensions that can do this?
    • mdaniel 8 days ago |
      Fastmail thinks JMAP is the future of mobile(?) email API access

      Also, I am just curious if you're unhappy with their android app? I find it very full featured

      • encom 8 days ago |
        Fastmail is a webapp, and it's very obvious. I use it out of laziness, because I don't use email on my phone that much. I wish they'd make a proper mobile client, but I don't think they care, since it's been like this forever.
        • mdaniel 8 days ago |
          OT1H, I don't have a horse in the fight about whether you're right or not, but I was curious because if it is a web app they did a damn stellar job

          But no, it's a formal android app and I offer two pieces of supporting evidence: the resource browser shows the apk very obviously has a bazillion android resource files <https://imgur.com/a/pUbQ8Bp> and it supports native fingerprint auth

          • FredFS456 8 days ago |
            I dunno if it's native or not, but the Fastmail app doesn't work when you're offline.
          • kelnos 8 days ago |
            I'm not sure why it doesn't work offline, then. The UI refuses to load at all if I don't have an internet connection.

            Native fingerprint auth can be implemented on top of a webapp; that isn't evidence either way.

            • altairprime 8 days ago |
              Native app doesn’t guarantee “caches data for offline access”.
              • kelnos 8 days ago |
                True. I seem to remember that the UI itself did not load when there's no internet connection, but I just tried it, and it does now. So maybe things have changed, or I misremembered.

                Either way, no offline access in an email app... pretty bad.

          • marcellus23 8 days ago |
            It's not a native app. The main interface where you view your mailboxes, compose new emails, edit settings etc is a web view. The interface doesn't even load if you're offline, let alone your emails. Certainly some parts of the UI are native, but that's true of any web app.
    • kayson 8 days ago |
      Yes! They just moved the settings around compared to K-9. You have to open the folders side bar, hit Manage Folders, then tap your folder and turn on "Enable Push" (and probably Sync and Notifications too). Annoying that you have to do this manually for every folder but it does work great!
    • cocok 8 days ago |
      > Is there any way to get push notifications instead of polling?

      Push support has been there for a long time now. You can enable it on a per-folder basis, check in Manage folders.

      • carstenhag 8 days ago |
        How would a true push (and not poll) method work, if all you have is the local thunderbird client? If I had to guess, the question from the other person is not related to mail poll/push stuff

        Usually you rely on a server telling the mobile app that there's something new to poll (or the message is directly sent and displayed).

        • dvdkon 8 days ago |
          A TCP connection to the IMAP server is kept open, with the server sending a packet whenever anything interesting happens (see IMAP IDLE), waking up the client app. This is how all push notifications work nowadays, IIRC, since you can't send information directly to clients without a persistent connection, due to NAT.
  • vzaliva 8 days ago |
    I do not know how it is financed, but I would rather have them use these funds to fix desktop version first.

    Content advisory: longish rant ahead.

    I have 4 email accounts: 2 Gmail, 1 Outlook, and 1 ProtonMail. I also use Google Calendar and Outlook Calendar. The reason I switched to Thunderbird was to manage them all in one uniform UI instead of keeping 6 open tabs.

    I tried hard to love it, but after about 6 months, I am ready to give up. The main annoyance is that I cannot see sent and received messages in a single thread. I know this feature is coming soon, but I do not know how long to wait.

    The second problem is that Thunderbird’s search, frankly, sucks. For example, while focused on a folder, if I start a search, it doesn't automatically narrow it to that folder; it searches across all my mail. I've noticed that when I need to find something, I open the Gmail web interface.

    Finally, there are bugs. Most of them are relatively minor, but combined, they ruin my user experience. There are strange calendar event reminders that will not go away, bugs when event modifications do not sync to the server, and the most bizarre bug: when I reply to my own message, it sets the FROM field to one of the recipients, making it look like I’m faking someone’s email. Sometimes, when I reply to an HTML-heavy message, the editor in my reply starts in white font on a white background, so I cannot see what I’m typing until I change it. Etc.

    I do not want to belittle the hard work all the developers put into Thunderbird. It’s a very complex piece of open-source software that does many good things. It just seems to fall a little short.

    So, I am seriously contemplating giving up and going back to the web interfaces for my respective email accounts.

    • JAM1971 8 days ago |
      1) You can see replies/sent messages in Conversation/Threaded view (I do this). Unfortunately I don't recall exactly how I set this up, but this might get you there: https://www.reddit.com/r/Thunderbird/comments/tvb02t/show_re...

      2) Expression Search NG might solve your search issues: https://addons.thunderbird.net/en-us/thunderbird/addon/expre...

      • vzaliva 8 days ago |
        On your #1 issue: it’s a well-known and acknowledged problem. Basically, the current Thunderbird doesn’t have unique message IDs across folders, which causes issues when displaying messages from different folders in threaded view. One of the common workarounds involves making copies of Sent messages in other folders like INBOX.

        There’s a major internal message storage rework project happening in Thunderbird, which should fix this once completed. You can try it in some beta builds, but of course, it’s still beta and isn’t compatible with some plugins yet. Most notably, the TBSync plugin, which provides Microsoft Outlook integration, doesn’t support it at this stage.

        • 1718627440 7 days ago |
          That is weird, because it works for me and I've never noticed, that it didn't worked in the past. (Thunderbird 115.5.0 on Debian)
    • aidenn0 8 days ago |
      Gnome evolution works great; I've used it with everything you are talking about except ProtonMail.

      It defaults to the bizarre Gnome look (no native controls, toolbar buttons haphazardly strewn through the title bar), but you can change it in the preferences if you hate that as much as I do.

      • zahllos 8 days ago |
        I have been using evolution as well.

        I have a relatively niche use case where thunderbird would no longer find my smime certificate on my smart card. But only in the compose/send UI, not in settings.

        While I understand not many people are doing this, it also... Used to work, and I would have thought that detecting regressions in X.509 cert validation should be well covered by tests.

        In comparison, evolution works.

      • cozzyd 7 days ago |
        I ended up having to switch ti Thunderbird because my work email turned off its imap connector and evolution didn't support the exchange 2fa they are using. Maybe it's supported now? I did prefer evolution to Thunderbird. .
        • aidenn0 7 days ago |
          I've been using Evolution with EWS MFA via Oauth2 for years; there's a tiny bit of extra configuration though:

          https://wiki.gnome.org/Apps/Evolution/EWS/OAuth2

          • cozzyd 7 days ago |
            I think I tried this but it wasn't supported by our Exchange setup for whatever reason that I can't remember. I might try again at some point though...
            • aidenn0 7 days ago |
              Another option to try is davmail; it exports davmail/caldav/carddav/LDAP from an exchange server.

              My only note with that is the caldav and exchanges internal handling of event invites will fight with each other, so don't try to accept invites from within your imap mail client.

      Maybe I'm missing what you're trying to do, but doesn't Ctrl-Shift-k "search" (called filter) on a per-folder basis? Testing for myself, I can filter by the basics, including body, and have it filter on a my focused folder

      You can donate to Thunderbird in general. Right on the homepage of Thunderbird mobile [1], is a donation link. [2] Unlike donations on mozilla.org, where the funds go to Mozilla Foundation (and not to Mozilla Corporation, which is the one developing Firefox), the donations on thunderbird.net go to funding Thunderbird on all the platforms that the Thunderbird team works on.

    Right when there are better alternatives (fastmail, proton, etc). Another bonus-worthy move by Mozilla's CEO!
    • callahad 8 days ago |
      Thunderbird is housed in MZLA Technologies, an independent subsidiary of the Mozilla Foundation and completely separate from the Mozilla Corporation or its CEO's remit.
    • advisedwang 8 days ago |
      Thunderbird is an email client, not an email service. Fastmail and proton only allow you to connect to their service. Thunderbird can use any IMAP/POP + SMTP email service.
      • pluc 7 days ago |
        Yes, but they provide their own apps.
  • kelnos 8 days ago |
    I use Fastmail, and have found their Android app to be functional, but lackluster (no offline access being one of my biggest gripes). I hadn't used Thunderbird on the desktop in a good 15-20 years, so I figured I'd give this a try.

    It is very snappy (unlike how I remember desktop Thunderbird all those years ago), and seems to work well so far, though it's a little bare-bones feature-wise. One thing that is unfortunate is it doesn't appear to be able to recognize Fastmail's "pinned" messages and map them to "starred" messages. That alone will keep Fastmail's own app on my phone.

    Fastmail also has different actions for marking as spam and reporting phishing; I'm not sure how effective the latter is, but of course Thunderbird doesn't support it, as presumably that's a Fastmail-proprietary thing.

    I'll probably keep it and see if it can serve as my daily driver, with the Fastmail app as a fallback for pinned messages for now.

    • wheels 7 days ago |
      It's not surprising that this feels different than Thunderbird as it's a completely separate app with a separate background just being rebranded with Thunderbird identity. There's probably some effort to make them play nice together, but K-9's been around for ages (I think I've been using it for more than a decade).
      • kelnos 7 days ago |
        Sure, I'm aware. I tried K-9 many many years ago but didn't really like it. Seems like it's more my style now (or my style has changed).
        • dizhn 7 days ago |
          It had a visual overhaul a few years ago. Not something drastic but it was a very positive improvement.
          • pmontra 7 days ago |
            And very negative for the people that selected K9 precisely because of the peculiar UX. 5.600 has been the last good version for me. I still sideload it on every new Android device I buy.

      I don't think there's anything proprietary going on, so I did a quick search. Fastmail supports JMAP [0], and JMAP [1] supports setting special keywords [2] for a message to mark it as spam of phishing. It may be possible to get this to work.

      • kelnos 7 days ago |
        Ah interesting. Looks like that's strangely specific to JMAP and not a generic mail header or something like that, so K-9 won't be able to do it, as it doesn't (yet) support JMAP.
  • pomian 7 days ago |
    This is great. I suppose the improvements will arrive soon. I used to use Thunderbird on Android long ago. (K-9 has done it's part in filling the gap sincce then.) It has always been a neat system to use - Thunderbird on desktops, and on cell phones(used to be on iphones also, I think.) though not linked, the same freedom of self mail control. A very good way to archive all your mail, as you want, without externalities. IMAP and PoP.

    After decades of a love/hate relationship with thunderbird mail reader, I sure hope this isn't the beginning of the end of decent email on android 8-/

    K-9 also has it's faults, but it's been a pretty good ophone mail reader.

    Thunderbird, under the ever declining mozilla foundation's wing, continues to make nonsensical changes while still failing to fetch mail into all IMAP folders (among a number of other fundamental functional failures).

    Nice but there are a zillion mobile e-mail clients already. What I really wish is a good desktop e-mail client for Linux that I can use for enterprise use: - Thunderbird is heavy, slow and the UI feels dated - KMail was very advanced 15-20 years ago but it's lagged behind and even HTML e-mail is semibroken today - evolution... well, let's say it has not really evolved in the past 10 years, since Red Hat lost interest in the desktop - others (Geary, Trojita, etc) are toys and unfit for enterprise usage

    Moving an item to the trash in Android TB (IMAP) doesn't seem to actually move it on the server. Webmail still shows it in the inbox. I see it in the trash in Android, but it refuses to let me move it out of the trash there, saying, "Cannot copy or move a message that is not synchronized with the server". The synchronize button and restarting don't have an effect.

    Is this a bug or do I have some misunderstanding about IMAP and a misconfiguration?

    K-9 deletes as expected.

    Am I crazy or is it a bad idea to download all your emails into your phone?

    Other than nostalgia, what makes this email client so special?

    Does it do NNTP?

    It's sad what cketti did to K9 after 5.6. I don't have any hope for the future of K9/Android Thunderbird anymore.
