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 should be familiar to Vim users. This package will install Pentadactyl for all users on the system. Users will be prompted to activate the extension when starting Firefox. To build the package for a Firefox version different from the installed one, start the script setting the FIREFOX variable as in FIREFOX=33.0.0
