Tab Utilities provides you with complete control over your Firefox browser tabs. You can fully customize the opening behavior of new tabs based on the link type (URL, Favorite, History, Search) and define how the should be focused and added to the tab bar. You can also customize tab closing behavior, auto-close unused blank tabs, restore closed tabs, navigate through tabs via keyboard shortcuts or you mouse wheel, and much more. Tab Utilities can even `faviconize` a tab, thereby reducing it to a small icon in the tab bar, or protect selected tabs from being accidentally closed. Tons of other features include custom tab highlighting (set color for tab types) , custom mouse-click menus (access tab history, load URLs from clipboard...), and much more. Excellent add-on for power users!
