Conkeror is a free, keyboard-driven, Mozilla-based web browser. It borrows as many key bindings as it can from GNU Emacs. It was written by Shawn Betts, the primary author of ratpoison and Stumpwm. Formerly a Mozilla Firefox extension, it is now developed for XULRunner as a stand-alone application. Development of Conkeror as a Firefox Extension was abandoned in 2007, but the archives of this remain available at http://downloads.mozdev.org/conkeror/.
