Thunderbird

Recent versions (90.0+) are highly unstable - a few weeks back it took me several days to rebuild my email library (150k emails [no attachments] spanning 20 years of work); new install, complete rebuild, then pow, same problem - crashes on start - start all over again. have been long time user, unwilling to use Apple Mail and looking now for alternatives to TB)

It's good that this app gets updated frequently. But the interface still looks so archaic.

Link is incorrect for 91.0.1 download - should be: <https://download.mozilla.org/?product=thunderbird-91.0.1-SSL&os=osx&lang=en-GB>

Hope, I will contact with all my friends faster)

TB 78.10.0 doesn't run on Big Sur (11.2.3)! I got an info-message: Your system doesn't meet the requirements to run Thunderbird. the requirements: Mac Operating Systems macOS 10.9 macOS 10.10 macOS 10.11 macOS 10.12 macOS 10.13 macOS 10.14 macOS 10.15

Nice and secure

I switched to Thunderbird many years ago after Apple Mail stopped working for me on my email account. I really like it, but miss the functionality of a "send later" plug-in for email messages. I hope a developer can update that in the future as it's quite useful!

I have been using it for three years. Love the integration with calendar and contacts. Search function works well.

This is the best email reader ever!

les polices sont beaucoup trop petites ,pas facile pour les mal voyant. je n'ai gardé l'application qu'une heure malgré cela l'application est facile a manipuler

Habe mich dagegen entschieden, da man die Konten und Ordner nicht aus der Vorgängerversion transferieren kann. Sie alle neu zu erstellen, ist mir zu viel Arbeit. Insofern bin ich sehr enttäuscht über dieses no go.

It does everything I need. Never had a problem. Regular updates. Somewhat clunky but heck it's just email.

Glad to see TB back in development. it could use some minor tweaks, though. The text in the main window is much too small, it would be nice to see it adjustable for farsighted folks. And the process for adding calendars is still cumbersome, and even broken. It isn't easy to add iCloud calendars or even Google Calendars (that option is completely gone). Hopefully this will be fixed soon. And I am completely amazed at all of the people complaining about the update to v78. Did none of you even bother to read the release notes? Might help. Especially those who are complaining about broken addons. [Hint: https://www.thunderbird.net/en-US/thunderbird/78.0/releasenotes/]

I like Thunderbird especially v68.x due to all extensions and internal features.. but v78, if you don't use PGP (who really use PGP..?), seems to be for me at least a kind of "kickback" : a lot of features aren't no more available and customizing TH78 is more restricted. Furthermore still not possible to change the font size of messages list, all Retina Macusers know what I mean. It's a pity that's not implemented again; old third party extension doesn't work since a long time. Updating TH68 database to TH78 seems also not easy.. Finally looking for another Mac email solution in the near future. But not for Apple's email client.

Excellent.

1. I really like Thunderbird but 2. it is just crazy that at least for me 100 % of the extension I am using stopped working with release 78. I am only using extension with a high user community. Not something really special, So be careful before updating, check the support of your extensions and make a copy of the Thunderbird profile folder before updating to 78. Just in case you need to downgrade again to the older release.

It does not upload new versions from 68.6.0 and asks you to download it. Then after deleting App from Applications and dragging new version into Apps the loader can be ejected, but comes out again as soon as you try and open the new App. It then offers you the chance to keep your existing profile, but the dock icon and the App in the Apps folder is not open properly. It is compromised by poor code as, otherwise it would load automatically on the upgrade, which it does not do. All the advice on Mozilla Support does not work with this problem. It seems that Thunderbird have given up any sense of integrity in this App. I have always been able ti update until 68.6.0. The code is wrong in the updates now and everone says that here is not a problem, but I have an iMac just over a year old and the latest OSX which is always up to date and my computer works flawlessly it's just that I have to say using 68.6.0 whether I like it or not.

Thunderbird has NO Mac OSX integration, it can not even handle in line images without having a fit. This is a pathetic effort on the part of Mozilla to pass off crap to Mac users. Don't even bother!

finally decided to move from Spark to TB. I like when I can SEE 30 or more emails in a short space, in one line each, without any icons and stuff like that. In Spark you can scroll and scroll down in order not to mis any email, because each email is quite large and looks nice, but takes up space. In comparison, TB lets you see a LOT of emails, all together, in one line each, although in a much smaller font size. But that's ok in regards to functionality. So, TB is most effective in its simplicity.

I again and again try to use TB. I like it, but I have 2 big problems: 1. To paste an HTML text is catastrophic. 2. Size of the subject/composing text font is tiny, and there is now way to adjust it. These two problems are obviously connected to handling of HTML. How come in so many years of development, these two problems still remain ? Please fix them.
