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. Additional web-specific features, such as our ‘Hint’ mode, command interface, and key bindings to automatically follow back and forward links, make it easy to navigate without touching the mouse and give Pentadactyl a habit forming nature of its own.
Pentadactyl is a fork of the Vimperator project by most of its primary developers. Major differences include a 7-fold startup speed improvement and other speed improvements elsewhere, the command-line is hidden by default, better private mode and :sanitize support, better forward and reverse incremental find support, and the ability to separate multiple Ex commands with a |.
