In 2006 we listed ten extensions whose only job was managing your other extensions: uninstallers, backup tools, mass installers and a button to restart Firefox. None of them work today; Firefox replaced its old add-on system in 2017, and the built-in Add-ons Manager now does almost everything those tools did. Here&#8217;s how to manage Firefox extensions in 2026.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-large wp-image-64917\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions-1024x538.webp\" alt=\"Manage Firefox extensions\" width=\"1024\" height=\"538\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions-1024x538.webp 1024w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions-300x158.webp 300w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions-150x79.webp 150w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions-768x403.webp 768w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/manage-firefox-extensions.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p><strong>Quick answer:<\/strong> Open the Add-ons Manager with Ctrl+Shift+A (Cmd+Shift+A on Mac) or go to <code>about:addons<\/code>. From there you can turn extensions on or off, remove them, check their permissions, allow them in private windows, set keyboard shortcuts and update them. Firefox Sync keeps your extensions the same on every computer, and Troubleshoot Mode starts Firefox with all extensions disabled to find a problem one.<\/p>\n<div id=\"ez-toc-container\"
