Thunderbird 149.0 dropped on March 24th with some useful additions and a longer-than-usual list of fixes.

The most practical addition involves the address book: you can finally select individual address book tabs and export them, without having to dump your entire contact collection every time. It’s a small thing, but anyone managing contacts across multiple systems has been feeling this pain for a while. Still on the address book front, creating new address books now happens through the Account Hub, centralizing account management a bit more.

For those using Exchange accounts via EWS (Microsoft’s protocol for corporate email), there’s another concrete improvement: starred messages now stay starred when switching between devices. Previously, stars remained local, making them pretty useless in multi-machine environments.

On the fixes front, the changelog is quite hefty. Among the resolved issues: the “Replace All” function in the composer wouldn’t update plain text until you closed the window, the “Repair Text Encoding” command could duplicate recipients and attachments, and pressing Delete on the Trash folder would remove the folder without asking for confirmation. Also fixed was a crash during mail thread imports, and a bug where “After Send” filters weren’t working properly. They also corrected accessibility issues, hard-to-read link colors in dark themes, and several security vulnerabilities.

Thunderbird remains one of the few truly free and privacy-respecting desktop email clients. If you’re also looking for a quality email provider, Fastmail offers a 30-day free trial.
