このアドオンについて
Muttator is a free browser add-on for Thunderbird, which makes it look and behave like the Vim text editor. It has similar key bindings, and you could call it a modal mail client, as key bindings differ according to which mode you are in. It is similar to the Vimperator extension for Firefox.
