Thunderbird Community Forum

Hello. I have installed Thunderbird on my MacBook Air M3, unfortunately indexing does not work. When I open the Activity Monitor, ‘Indexing Messages’ appears in the list, but after 2 hours it is still at zero, the first few were made in the first millisecond. What can I do? Thank you for your answer

Hello, I have had to re-install Thunderbird after a disastrous upgrade to a more recent macOS, and subsequent downgrade. I thought that all my information would be preserved in the various Time Machine backups that I have made. However, all of my local folders containing 18 years' of email correspondece have disappeared. I can only view emails which are stored on the remote IMAP server. Any assistance would be greatly appreciated. Kind regards, John.

I tried to transfer the Profile of Thunderbird Version 115 from my Windows 10 PC to a new Windows 11 PC. I followed the steps posted at the website ( https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer ) I got to Step 5 for the new / destination computer 5. Locate the "Profile Folder" entry, but when I clicked Open Folder. Windows could not find the Thunderbird profile folder How do I bring my Thunderbird profile to the current version of Thunderbird? Thank you

How can I restore Thunderbird settings and/or emails that were lost in the upgrade to version 128.2 (for Ubuntu)? Files for the previous version are still in the hidden .thunderbird folder on my hard disc, but the new version won't recognise them (even if I move them into the snap/thunderbird folder. I have an email backup, but version 128.2 doesn't seem to have a way to restore backed-up emails.

I'm running for quite a time Thunderbird on Windows up to Win11 without any problem. For about 3 years I'm using the same TB profile in dual boot environment with Linux Mint (v21 until last week and now version 22). I understood why I didn't get access from Linux side after the latest TB update in Windows as obviously the file structure and other things had changed to make it incompatible to elder versions.

However, as Linux is now my normal working environment, I've tried it again after upgraded my system to Linux Mint 22 Cinnamon 6.2.9 , kernel 6.8.0-44-generic and failed again, having the same error message when starting the profile: "Thunderbird is already running, but not responding. To use Thunderbird, you must first close the existing process, restart your device, ore use a different profile. "sudo killall Thunderbird" didn't find a running process.

I've tried importing everything in a new profile, which worked (more or less), but failed with all attempts getting access to my local profile. A local profile appears after importing but contains no data, trying to import its data separately doesn't trigger any error message when just ticking "E-Mail", but nothing is imported. When ticking "E-Mail" and "Settings", I'm getting a red alert that asks me to look into the error console which doesn't help either.

What can I do ????

just updated to 128.2.0esr, the custom userChrome.css is not applied anymore and I got back to see the ugly yellow warning instead of the muted grey one I overridden in the css, that always worked so nicely

@namespace html url("http://www.w3.org/1999/xhtml"); html|div.container.infobar[role="alert"] {

 background-color: grey !important;
 height: 20px;

}

was there a hidden update to how that file is handled?

(the about:config toolkit.legacyUserProfileCustomizations.stylesheets is still set to true)
