Thunderbird 137 Released with Important Fixes and Improvements
Mozilla has officially released Thunderbird 137, the latest version of its popular open-source email, calendar, and news client. While this update doesn’t introduce any groundbreaking new features, it brings a series of critical bug fixes and enhancements that refine the user experience across platforms.
No Major Features, But Notable Tweaks
Unlike past releases that introduced new tools or interface changes, Thunderbird 137 focuses on polishing what’s already in place. The most visible change is the addition of a donation splash screen, which appears to encourage users to support ongoing development.
On the Linux side, the update disables the system tray icon for now, citing a lack of proper functionality. Developers intend to restore it once it works reliably. Meanwhile, Windows users benefit from a small but useful update: mail folders can now be stored using file names, making file management more intuitive.
Bug Fixes That Enhance Usability
Thunderbird 137 addresses several longstanding bugs:
High contrast mode: Fixed in-app notifications that previously failed to display correctly.
Edit menu issues: Resolved missing menu entries when selecting group headers in the “Grouped by sort” view.
IMAP folders: Corrected a bug where the “Undelete” function would perform a “Delete” when mixed messages were selected.
RSS feeds: Now allow users to scroll using the space bar, just like with regular emails.
Performance: Improved loading speed when opening
.emlfiles in profiles with many folders.Threaded search view: Now updates correctly when sorted by date.
Final Thoughts
Thunderbird 137 may not be a headline-grabbing release, but it serves as a reminder that stability and refinement are just as important as flashy features. If you’re already using Thunderbird, updating to the latest version will enhance your daily workflow, especially if you rely on high-contrast themes, RSS feeds, or manage numerous mail folders.
As always, you can download Thunderbird for free from the official website .
