Fresh from revealing more details on upcoming Thunderbird Pro features, MZLA Technologies has issued its latest monthly update for the esteemed open-source e-mail client.

Thunderbird 142 ships with a small set of iterative user-facing improvements, plus under-the-hood bug fixes, stability updates, and a fresh set of security patches to keep things running smoothly.

After updating to Thunderbird 142, you’ll find a new ‘Copy Message Link’ (or ‘Copy News Link’) options being the ‘More’ button menu of emails. These links can be pasted into a web browser and, so long as OS handling is set up, open the mail in Thunderbird.

If you’ve reordered folders for an email account and want to revert, you can now right-click on an account header in the left sidebar and select the ‘Reset folder order’ option to do just that. It’s also now possible to copy folders too.

Finally, rounding out the ‘noteworthy’ features, Thunderbird’s PDF viewer now lets you add signatures. Signatures can be typed out, drawn, or uploaded as an image, and you can save multiple signatures for future use, saving the need to re-draw/add them.

This release also squashes a slew of pesky bugs, including:

  • Notification sounds did not respect OS do-not-disturb mode
  • Fastmail users unable to use calendars due to missing OAuth settings
  • Sending from a unified or local folder failed if no default account set
  • Close button inactive if mouse was in the screen corner (Linux)
  • Contact photos in WebP format were not displayed from CardDAV servers
  • Microsoft Store version did not open when clicking ‘mailto:’ links
  • Initial launch had long load times and UI lag while messages downloaded

All now solved. Hurrah!

You’ll find a lick more detail in the release notes.

Download Thunderbird 142

Download Thunderbird for Linux, Windows, and macOS from the official website. Downloads now default to monthly release builds. As of writing, that will be Thunderbird 142 – but in the future 143, 144, and so on.

The Thunderbird Snap in Ubuntu is an ESR build, which updates to a slower cadence.

Those already using Thunderbird’s monthly releases can update through the method they installed from.

For standalone binary builds (linked above) updating happens in-app: open Thunderbird, then go to the Help menu and select About; it will check for and apply any available update. Restart to apply, and relaunch to enjoy!
