Check your list of extensions to see what is disabled. I don't see why you would want to install an extension to do that or to waste valuable space on the Toolbar when you can just use "'''Ctrl+Shift+T'''". * [https://support.mozilla.com/en-US/kb/Keyboard%20shortcuts Keyboard shortcuts | How to | Firefox Help] * [http://dmcritchie.mvps.org/firefox/keyboard.htm Firefox and other Browser Keyboard Shortcuts (Comparison Table)] * [http://dmcritchie.mvps.org/firefox/tabs.htm Tabbed Browsing in Firefox] * [http://dmcritchie.mvps.org/firefox/tabs_config.htm Tabs configuration, extracted from About:config entries - MozillaZine Knowledge Base] One of the following extensions may need to be updated, if not one of these it probably has "Tab" in its name. Disabled extensions appear at the end of the of the extensions listing ("about:addons"). * "Undo Closed Tabs Button" * "Toolbar Buttons" or If you don't want so many buttons in one extension you can choose individually from a list here:- http://codefisher.org/toolbar_button/toolbar_button_maker * "Tab Mix Plus" a bloated extension that keeps you from learning Firefox.
