Mozilla has just unveiled Thunderbird version 141 of its widely adopted free and open-source desktop email client, now available for download.
One of the new features introduced in this version is the ‘Archive‘ action now available right from mail notifications. Additionally, Thunderbird’s Composer now smartly warns users if their configured OpenPGP key is nearing expiration, helping to prevent sudden security issues.
As for fixes, there’s plenty in this update. For example, message archiving should now proceed smoothly, without silently stopping during asynchronous folder creation. Some of the other bug fixes worth noting include:
- Crash fixes: Thunderbird could previously crash when parsing message states or during POP3 startup—now patched.
- UI quirks: The status bar exhibited some odd behaviors, such as displaying old attachment information when hovering over new ones or failing to display hovered links properly. Those are sorted now.
- Search and organization woes: Ever had trouble finding contacts with phone numbers containing periods? Or noticed folders not sorting correctly? Yes, fixed.

Lastly, please note that there’s still an unresolved issue: passwords aren’t remembered when using 32-bit MAPI without opening a compose window—so keep an eye out for future fixes.
