Gnome Adwaita GTK4 Dark Scotty Trees מאת

For additional settings to tweak to get a more pure Gnome Adwaita look, see below: (list updated as of 04.2026)

Firefox Color add-on is limited in what it can change, and that is by design for compatibility, so I've created this extra section for setting(s) I've found that allow for an even more pure Gnome Adwaita experience, while still maintaining compatibility with Firefox updates so nothing is ever broken!

Tweak #1: Enables rounded corners on the bottom of Firefox window border

1. Type about:config in the address bar and press Enter.
2. A warning page may appear. Click Accept the Risk and Continue to go to the about:config page.
3. In the 'Search preference name' panel, type widget.gtk.rounded-bottom-corners
4. Set value to TRUE allows rounded corners. Default value is FALSE if you want to revert the change. Changes take effect instantly, no need to restart your browser.
5. ENJOY!
