This is going in the correct direction.

If Firefox provides the correct API's we might have the power of vimperiator back. Off the top of my head it needs:

1. A way to load config from the filesystem so I can keep its config with my other dotfiles

2. To be able to work on about:addons etc

3. To work in reader mode

4. Vim keybindings in textareas/inputs (although for modularity this could be a separate addon).

5. A way to open textareas etc in an editor - again for modularity this could be a separate addon.

6. Be able to open file://

7. A way to focus on the page content (away from e.g. url bar) - this could be a FF level hotkey though.

EDITED - I'm adding things as they come up.
