FoxOne

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

Tested with Firefox 158 on Windows, macOS and Linux (GNOME) 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 – bug hunting, ideas and the urlbar and corner fixes
• @snkiz – nav button hover delay, hide-disabled option and the extension cluster rework
• @atrehhoff – new tab button, spacing and macOS testing
• @DeathMurderGod – minimum tab width and the original auto-hide nav buttons
