A collection of userChromeJS scripts and legacy-style Firefox extensions loaded via autoconfig.js, enabling deep customization of Firefox and Thunderbird without restarts. It includes a loader/manager (rebuild_userChrome.uc.js) plus scripts for media control, UI tweaks, and more.
Use cases
- customize Firefox UI with userChromeJS scripts
- load unsigned extensions in modern Firefox
- control media playback across tabs with hotkeys
- manage and toggle browser scripts without restarting Firefox
- apply the same customizations to Thunderbird
When to choose
- you want deep, scriptable customization of Firefox beyond what WebExtensions allow
- you need to run legacy-style extensions or userChrome scripts on current Firefox versions
- you want restartless script management with a toolbar button
When to avoid
- you only need standard add-ons from Mozilla's store
- you're uncomfortable modifying the Firefox installation folder and profile
- you need something that survives Firefox's frequent internal API changes without maintenance
