This was mistakenly posted in the Firefox stream. Amended with apologies.

The latest Snap update on my Kubuntu laptop is marked as a BETA version. I haven't selected the BETA stream, and I checked and snap seems to be pointed at the stable version.

I like to keep track of changes at each install and there's no Release Notes available.

Is this an error at your end or do I need to change something to get back to a stable version?

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.

Thunderbird did update while Thunderbird was running. Notice no new emails a few hours later. Icon changed to text picture and all folders showing. Received request if I wanted text icon removed? Said yes. Everything gone. Went to program file, x86 file and only file in Thunderbird visable last nigher were update logs. Now gone, everything in Mozilla maintenance folders gone.

Appdata shows 8/10 profile. Mobile email link to Thunderbird down, not receiving.

When I up dated the latest version of T.B.. when switching form the index desk top page to read the email, the page is blank EXCEPT for "SWITCH TO: EXTENSION" displayed at the top of the page

The T.B. icon is not is not displayed

From the release page of Thunderbird - https://www.thunderbird.net/en-US/thunderbird/releases/

I see 153.0 (the first release) is marked as ''esr'. But from 153.0.1, there are both esr and release. I would be great to understand the reason behind this approach.

Thanks in advance!

Dear Foristi, after updating to V. 135 Oesr (64Bit), neither AOL mail nor Yahoo mail cooperate any longer. Passwords checked, correct. Other PC, not updated, still connects to AOL and Yahoo addresses without flaw. OS: Linux Mint, both PC have 8 GB RAM. Where did I screw up?

Thanxalot in advance -rick

I believe I downloaded 153, but I don't where to find it.

The information regarding Version 153 and downloading it is confusing.

One page states, "Manual upgrade to 153 is now enabled via Help > About", but when I go to Help > About, all I see is the current version and the statement that it is up to date. The recommendation on one page regarding 153 is to switch from Release to ESR, although the contrary seems to be the case for Version 153.

End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

After running an update, when launching Thunderbird it says "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?". Rebooting does nothing, I'm prompted with the same message. Tried re-installing the latest version - it gives me the same error message before re-installying, and also un-installing the version I have on my PC - it also prompts me to restart to finish the earlier upgrade.

I'm up to date on Windows 10 with version 151.0.1 of Thunderbird. My preference is to discontinue using Windows and move to Linux Mint. The Software Manager in Mint installs and manages Thunderbird updates. I like the idea of Mint managing my software. However, the latest version is 140.11.1esr. Consequently, moving my data from Windows to Mint is not possible. A profile problem is flagged.

I've switched off automatic updates. I'm wondering how long it will take Linux Mint to catch up to v150. One solution is to install v150 independent of the Mint software manager, but I'd rather not do that. I'm wondering if there are any workarounds.

French please !

Bonjour,

Lorsque je veux modifier la manière dont Thunderbird est mis à jour, il s'affiche ceci :

"Thunderbird est mis à jour par une autre instance" et il est impossible de le modifier car si on on choisit de le faire, le logiciel thunderbird corrige immédiatement et retourne à la configuration précédente (solutions/choix à cocher, mises à jour automatiques ou manuelles) !

Comment opérer S.V.P. ? Merci à vous. Salutations cordiales. Alain.

I opened Thunderbird 140.9.1esr from flatpak on Debian 12 and today I noticed a message that says: "Flatpak ESR application ID change We're switching the Flatpak ESR application ID from org.mozilla.Thunderbird to org.mozilla.thunderbord_esr."

1. How does Thunderbird know it's flatpak name is changing? How do i turn off all auto updates including checking things like flatpak name changing?

It would have been highly beneficial to provide a function or procedure to migrate all files (if they existed) from org.mozilla.Thunderbird to org.mozilla.thunderbird. In the absence of such a mechanism, the update effectively behaves like a fresh installation, creating the impression that all user settings and data have been lost.

I resolved the issue by manually copying all files from /home/USER_NAME/.var/app/org.mozilla.Thunderbird/ to /home/USER_NAME/.var/app/org.mozilla.thunderbird/ and restarting Thunderbird, after which everything functioned as expected. This could also have been addressed through a symbolic link to the new path.

I believe more care should be taken when implementing breaking changes of this nature, as many end-users would not know how to resolve this issue on their own. Clear guidance or automated migration would help prevent unnecessary disruption and confusion.

May 25 2026. A few days ago, Thunderbird upgraded me to Release 151.0. I can no longer send or receive emails.

My wife has been upgraded to ESR 140.11.Oesr, and she has no problems.

I do not want to go through the tests of removing virus guard etc to try to make 151.0 work, so I would like to move to ESR 140.11, but cannot find online how to do that?

Please help.
