tridactyl has a similar feature. It let's you break out the edit-pane content into a real vim/gvim editor (default <c-i>). There you have all your vim environment. I use this feature very rarely, e.g. when writing multiple lines in comments and I am in need of the editing power of vim. For simple text input I remain in the browser ui. Getting a vim-editor in all text inputs would be too much for my taste.
