Форум поддержки Thunderbird

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

Ever since the last "upgrade" which is terrible I get my emails in threads. Does anyone know how to get rid of the stupid threaded messages? I've tried everything. All I want is emails to be listed in the order I received them. I DO NOT WANT THREADS

Just trying to upload my email account. It has only partially completed the upload. Files are missing and alterations I made to my actual email account are not showing. Tried taking it off and reloading but has exactly the same errors!

Windows 10 22H2, Thunderbird 115.5

Thunderbird periodically loses my saved passwords (11 accounts) necessitating the re-entry of said passwords. This has been happening for about six to eight months.

I have searched for solutions and have tried deleting the pkcs11.txt and secmod.db files but the problem reoccurs. There is no rhyme or reason as to how often this happens. If I new where the passwords were stored, I could copy the good password file back into the thunderbird directory.

Any suggestions would be greatly appreciated.

Thanks.

I recently reset my desk top and after that my thunderbird will not open without a password that I have not got. I need a simple way to find the password or otherwise allow me to reinstal a new download. I have tried for two days using lots of suggestions from web and help but I cant get past the request for a password

I get this message when I try to get to the window to enter my password: 400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

'Hola, I still have message ID & user agent & X account key in the header of my emails, along with the date. I NEVER had them before; I don't need them. How do I get rid of them?

The ability to change font size is disabled. I lost my User profile on my PC, and I am starting from scratch with all settings. My custom folders are still there, but I have had to recreate message filter rules, and I can't get the font large enough to read.

Note: When I click on the image I provide below, it makes it look like my font size is huge. It is not.

As everyone here knows, Thunderbird 115 is a hot mess; sadly, as they cycle through new releases, it sometimes gets worse, not better. It appears from my update history that 115.2.3 was the most stable of the 115 versions. I'd rather go back to 102 but it seems that the profile was modified in 115 so that it is no longer compatible with 102. Thus a 102 rollback might require quite a bit of work to reimport the profile into a clean install. And I have gigabytes of important mail.

I'm not on 115.4.3 and it is close to unusable, as they screwed up regression in a major bug, and my bugzilla on it has sat unanswered, other than requesting I be nice to the devs. So as a lower-risk option might be to roll back from 115.4.3 to 115.2.3. Has anyone tried anything like that, or know the safest way? I don't know what booby traps they've planted to prevent any rollbacks. Thanks!

My office is running Thunderbird 115. I recently changed the password. This seemed to work OK. But on restarting TB I found the new password had not been stored. The Password Manager display is empty, so I cannot edit anything, nor can I insert a new entry into the Manager. I want to store the current password. How do I do this?

Even though highlighting text is a SUPER minor feature, it is one I would love to see in Thunderbird. I am using Release 115.6.1 (64-bit) and would love to have that capability. I searched for add-ons but the only one I found had been withdrawn by its author. Please advise if that capability exists and how to install it. Thanks, mkcgkc@gmail.com Ken Cawthorne

Your instructions for unthreading do not work. The commands you suggest do not appear in my "View" folder. And I do not want to unthreads many dozens of folders manually.

Please provide guidance on how to fix this, or I will have to abandon Thunderbird (which I have used loyally for many years) or work via the Gmail platform (ugh).

I'm having trouble with my Thunderbird password. I have 2 emails with identical settings and passwords. One works fine. The other's asking me for my password. When I enter what I knew for certain was the password I get the message, "Login to server imap.comcast.net with username weissfamily@comcast.net failed." I successfully changed the password still get the same error message. Also I get a Thunderbird popup that says, "Alert from account weissfamily@comcast.net: 1014." This is all above my pay grade. Need assistance. TIA. Tim Weiss

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

Upon reopening Thunderbird mail today, I find that the latest update does not allow emails to be opened in a new window with one-click. Clicking on an email launches the message in a new tab instead of a window. Why create a new issue like this? DUMB . . . please fix.
