You can remove the add-on in a number of ways. Here are two options: (1) If an add-on has a toolbar button, or appears on the Extensions button drop-down list, right-click > Remove Extension ''More info on the Extensions button:'' [[Manage your extensions using the extensions button in the toolbar]] (2) Go to the Add-ons page and remove the extension there. Here's how: Call up the page using either: * Ctrl+Shift+a (Mac: Command+Shift+a) * "3-bar" menu button (or Tools menu) > Add-ons * type or paste '''about:addons''' in the address bar and press Enter/Return In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading. Your currently enabled extensions should be listed. Next to the blue slider switch, look for a menu button (3 dots in a row) and click that to find the Remove option. Success?
