A Vim-like, five-fingered interface for Firefox and other XULRunner-based apps.

Pentadactyl is a free browser add-on for Firefox, designed to make browsing more efficient and especially more keyboard accessible. Largely inspired by the Vim text editor, the appearance and finger feel of Pentadactyl should be familiar to Vim users.

Dactyl is a fork of the Vimperator project by most of its primary developers.
