I'm still using Pentadactyl, which is incredible, but it's almost certainly doomed. You'll need to use the signed version on github: https://github.com/willsALMANJ/pentadactyl-signed You might consider Vimperator, which is similar, but inferior iny opinion. It has better support, though, and is more likely to survive into the future.

If you're looking for something simple, VimFX works, but it's too basic for me. Not sure of the future of VimFX.
