✨ New

Updated to Firefox 138.0.4

Better compact mode support for multiple toolbars.

🐞 Bug Fixes

Compact mode showing 'tab opened in the background' when having multiple toolbars.

An issue with GTK popups having low contrast.

Tabs not being able to unload after closing Glance.

An issue with updating invalid mods clearing the mod list.

An accessibility issue with the scrollbar on the sidebar.

Opening a new link in split view while having Glance open.

'All tabs' menu not showing any text when collapsed toolbar is enabled.

🚧 Breaking Changes

The customizable UI on the tab strip (located between the top and bottom icons) has been discontinued due to the way the internal layout functions—buttons placed in that area are automatically removed. While it’s possible to re-enable this feature by doing some hacky CSS, doing so may lead to instability or breakage, and is not officially supported.
