List of vim plugins I use - with mini tutorials
    […] I do all(not counting using the textarea inside the
    web browser) of my editing inside vim.

You can edit even textareas with the “It’s All Text!” Firefox addon (https://addons.mozilla.org/en-US/firefox/addon/its-all-text/). I’ve never used it, but I’ve read it’s the standard for Vim editing of browser text for Firefox users.
