Mozilla has released a new stable version of its open source Firefox web browser a moment ago.Firefox 145 is the latest version of the browser and it comes with several new features, improvements and changes.

On the feature side, Mozilla is adding support for PDF comments, which lets you add, edit or delete comments. There is also a handy option to reveal all tabs of a tab group and a new option to create links to specific parts of webpages. On the downside, support for 32-bit versions of Linux is ending with this release.

The Firefox Extended Support Releases (ESR) 140.5 and 115.30.0 are also released today. As usually, they focus on security fixes and bug fixes, but do not contain new features.
