Firefox 157 and later enable Nova UI by default. To restore Proton's smaller corners, set uc.flex.style-tab-items-border-radius = 1 and uc.flex.style-toolbar-items-border-radius = 1.
FlexFox has ended support for Firefox ESR 140 in line with Firefox's support schedule. Firefox ESR 153 is now the minimum supported version.
FlexFox no longer supports legacy pre-v6 styles left in Sidebery's Styles editor. Before updating, remove the old FlexFox styles from the Sidebar and Group Page tabs. See the upgrade instructions for details.

New
-
Added
uc.flex.increase-sidebery-hover-trigger-widthto make fully hidden Sidebery and native vertical tabs easier to reveal on multi-monitor setups. It widens the edge-hover area to22pxin maximized windows and F11 fullscreen mode.Disabled by default because the wider area may interfere with clicks near the webpage edge. Fine-tune the width with
--uc-sidebar-hover-trigger-widthin custom CSS.
Improvements
-
Reworked the built-in PDF viewer so its top toolbar and sidebar float and auto-hide independently. Both support translucent backgrounds with Mica, wallpapers, or
uc.flex.enable-translucent-urlbar-popup-and-menus. Adjust transparency withuc.flex.browser-*-transparency-level.
-
Unified container tab indicators in Sidebery and native vertical tabs. Regular tabs use short right-side markers that move with their titles, while pinned tabs use short bottom lines. Indicators remain visible above tab borders.
-
Smoothed the hover transitions of the pinned-tab and sidebar-tool separators in native vertical tabs.
Breaking Changes
- Moved FlexFox's preference file from the repository root to
config/user.js. For full-repository installations inside a Firefox profile, this prevents Git updates from restoringuser.jsat the profile root and resetting customized preferences on startup.
