<\/span><\/h2>\nOur original list included Fox Tab (3D tab browsing), Colorful Tabs, Firefox Showcase, Tab Renamizer, New Tab Homepage, Duplicate Tab, Basics, Tab Popup, Close and Forget and Too Many Tabs. When Firefox moved to its modern WebExtensions system in 2017 (Firefox Quantum), most of these old add-ons stopped working. Many of their features are now built into Firefox: duplicate a tab by right-clicking it and choosing Duplicate Tab<\/strong>, set any page as your new tab page in settings, and use tab groups and colours instead of Colorful Tabs.<\/p>\n<\/span>Frequently asked questions<\/span><\/h2>\n<\/span>Does Firefox have tab groups?<\/span><\/h3>\nYes. Firefox added native tab groups in 2025. Drag a tab onto another to create a group, then name it and pick a colour.<\/p>\n
<\/span>How do I turn on vertical tabs in Firefox?<\/span><\/h3>\nOpen Settings, go to General, and under Browser layout choose Vertical tabs. You can switch back to horizontal tabs the same way.<\/p>\n
<\/span>Which Firefox tab manager uses the least memory?<\/span><\/h3>\nOneTab and Auto Tab Discard help most with memory, because they unload tabs you aren’t using.<\/p>\n
