Thunderbird 142 Lands With Modest Upgrades - Plus Talk Of Pro Service Ahead
The Register, Friday, August 22nd, 2025
Bug fixes, message links, and hints of Exchange support in the pipeline
Mozilla-owned subsidiary MZLA has released a new version of the Thunderbird messaging client and shared details on the forthcoming paid Thunderbird Pro service.
Thunderbird 142 touched down at the same time as Firefox 142. The release notes list 25 bug fixes, and there's an additional list of fixed security vulnerabilities.
One of the less obvious but still useful features in Thunderbird is the ability to sort the contents of the folder list. It's the top-left pane in the main window, and it has a choice of views: All, Unread, Recent, and so on.
