Configure the Firefox and Thunderbird menus

This Mozilla extension allows you to configure which menu items will be displayed in the context menu (right-click) and the main toolbar menus to streamline your menues and make it easier to find the items that you use most.

Chose wether or not to display them at all or change the order in which they appear. You can also add line breaks to seperate groups of menu items that belong together.

MenuEditor even takes into account menu items added by other extensions that can quickly clutter up your menu space. A restore default button is handy in case you go to far and remove an option completely accidentally.
