Great but room for improvement. Rated 5 out of 5 stars
Great addon, offers the keyboard functionality of the vim, without sacrificing firefox own keyboard shortcuts, like ctrl+t etc.
Only one suggestion: firefox's option "search for text when I start typing" doesn't work together with vimium. The reason is that the hot key if the "f". Is it possible to change the default key from "f" to "space" so I keep the option "search for text when I start typing" enabled?
