Version 141.0, first offered to Release channel users on July 22, 2025

New
Now Firefox can help you keep your tabs organized, automatically. A local AI model identifies similar tabs, automatically organizes them into groups, and even suggests group names. Everything happens on your device to respect your privacy.

Vertical tabs users can now adjust the size of the tools areas at the bottom of the sidebar. To see fewer tools and more tabs, drag down the divider line which pushes extra tools into an overflow menu.

On Linux, Firefox uses less memory and no longer requires a forced restart after an update has been applied by a package manager.

Address autofill has been enabled for users in Brazil, Spain and Japan.

The Firefox address bar can now be used as a unit converter. The unit converter supports converting units of length, temperature, mass, force, and angular measurement, as well as timezones (e.g. “now in GMT” , “10am EDT to CET”). Selecting the result will copy it to your clipboard.

Firefox builds in Valencian now come with a built-in Catalan (Valencian variant) dictionary for the Firefox spellchecker.
