I was looking for a simple firefox extension to add minimal vim-like navigation to webpages.
New in version 1.1: configurable keys (see screenshot).
I already knew a lot of firefox shortcuts, so I didn't want to have to re-learn them all, I just wanted to add hjkl navigation so I don't have to use the arrow keys or my mouse to scroll a page.
