FoxOne

One-line layout, hover-reveal icons, dynamic bookmarks bar, floating Findbar, Gruvbox colors and ready for Nova

Tested with Firefox 157 on Windows, macOS, and Linux (GNOME & KDE) with browser.nova.enabled set to true

Install | Customise | See it in action

Over 40 variables for colors, layout and toggles. Missing something or found a bug? Open an Issue or a PR.

I use Firefox ESR, which release should I use?

• ESR 153 (with browser.nova.enabled) – use 3.5.2
• ESR 140 (with the classic pre-Nova UI) – use 2.3

Using Thunderbird? Take a look at BirdOne.

Special shoutout to @NeroWolfe75 for all the bug hunting & ideas!
