Hello folks,
I’ve developed my own userChrome.js script to make Firefox support multiple rows of tabs.
Highlights
-
Tab Groups Support: Fully supports mouse operations for tab groups — even in multi-row mode — delivering a smoother, more graceful experience. -
Enhanced Tab Animations: Adds fluid transitions for various tab-related actions. -
Optimized Space Usage: Makes full use of available UI space, including the area beneath window control buttons. -
Smooth Dragging Experience: Supports animated tab dragging even in multi-row mode. -
Pinned Tabs Grid Layout: Pinned tabs are fixed in a compact grid when Tabs Bar is scrollable — ideal for managing large numbers of pinned tabs. -
Customizable Preferences: Offers a rich set of options and features to tailor the experience precisely to your liking. -
Auto-Update Checker: Automatically checks for updates to ensure you’re always equipped with the latest enhancements and improvements.
