Rated 4 out of 5 stars
I recommend this for any Thunderbird users. With this addon, you can find out the menu item you want to use even if there are too many menu items in a menu.
To be honest I want to use CuteMenus Classic on Thunderbird, but I cannot do it because the addon doesn't support Thunderbird... anyway, this is still very useful.
