Yes I used to have one of this extensions, don't remember the name but was capable of editing with Vim all the textarea elements in every web page. To switch between firefox and xterm was not very comfortable at least with my window manager. What I could like more is an extension that can give vim features to the browser text area.
Btw there is something strange going on here: the textarea is the most popular text editor out there, the most used one where millions of people write short and long text every day, and still browser developers are not realizing that it should be improved.
