Is there a way to remove the context menu items in Firefox?
The Menu Wizzard Firefox add-on allows you to rearrange or remove menu items from the main context menu (right-click menu) and main menu bar (File, Edit, View etc.).
There were also Menu Editor and Menu Editor II Firefox's extension available to the market some time ago, but they are now both gone. First is gone completely and the development's of second one is ceased.
Menu Wizard is no longer available.
Custom Right-Click Menu is can be used as a remplacement.
