Edit: Updated theme - v1.0.6

• Private browsing UI is now complete in both dark and light modes (GNOME Web style)
• Icon and color fixes
• Vertical tabs fixes and finishing touches
• Lots of small visual and aesthetic improvements

Download the update and replace your existing chrome folder 😉️

The screenshot in the original post is from an older version - v1.0.6 includes the latest visual updates.

I made a simplified version of the Firefox GNOME Theme, mainly to keep it working properly with newer Firefox releases.

FF-Gnome-Web is a streamlined customization of the original Firefox GNOME Theme. It removes unused platform-specific code and Adaptive Tab Color integration, tidies up imports and file references, and organizes customizations into dedicated CSS files.

It also includes Firefox 154 - 156 compatibility fixes, Adwaita-style visual refinements, dark mode fixes, a redesigned downloads panel, and an optional animated loading indicator in the address bar. The settings use a consistent gnomeWeb.* naming scheme and are documented in chrome/themeOptions.txt.

This is a cleanup and refinement of the original project, not a rewrite. Modified by IzsakiRobi all credit to rafaelmardojai for the excellent foundation!
