FoxOne 3.0 - ready for Firefox Nova
This release brings FoxOne to the Nova UI. Tested and stable on Firefox 152+ with browser.nova.enabled.
Highlights
- One-line layout, now unconditional (dropped the 1000px breakpoint)
- Nova chrome reskinned: navbar, bookmarks bar, urlbar dropdown, search-mode switcher, split-view outline, sidebar/split splitters - all theme-adaptive in Gruvbox
- Dynamic toolbar support: up to two extension icons pinned by the hamburger, revealed on hover (replaces the old single static pin)
- New opt-ins:
--uc-hide-urlbar-buttons,--uc-hide-extension-icons - about:preferences / about:addons pinned to Gruvbox dark
- Scale-aware tab sizing (physical-px thresholds, DPI-correct)
- Docs synced with current CSS variables
- and much, much more...
Compatibility
Dual-written (Proton & Nova). Classic Firefox should still work but is no longer tested - use the 2.3 release for a known-good Proton build.
