Works!

can't use my browser without this plugin. just great.

Works very much like Vimium on Chrome. I've been a Tridactyl user before, but since the recent retraction from AMO, this addon has been a godsend.

A couple of things the developers got right with this extension:
- Navigating with j/k is smooth
- Extensions not too invasive as to mess up other browser shortcuts (e.g. Vim Vixen hijacks CTRL+F and I can't use regular find anymore).
