The ThunderBird Menu Editor is an add-on that lets you personalize your menus according to your preferences. With this tool, users can easily customize and edit their application menus.
Not only does Menu Editor work with Firefox, but it also supports Thunderbird. Simply install the extension, and you'll be able to customize the menus in both of these popular applications.
One thing to keep in mind is that Menu Editor requires Thunderbird version 1.1a1 to 1.5.0*. As long as you meet this requirement, though, you'll be able to take full advantage of this powerful and user-friendly menu customization tool.
