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 nifty new features introduced in this version is the ‘Archive‘ action now available right from mail notifications. That means you can quickly clear out your inbox without even opening the app fully.
Additionally, for those serious about security, 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. One annoying crash related to message parsing has been squashed, along with another that affected POP3 users during startup. And, if you’ve ever had trouble with Thunderbird mistakenly deleting attachments instead of entire messages, this issue is now sorted out.

Moreover, message archiving should now proceed smoothly, without silently stopping during asynchronous folder creation. Some of the other fixes 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.
