Tom Fitzsimmons showed me Conkeror while I was up in Toronto this past week. It is chrome for firefox that acts like Emacs. It features Emacs-style key bindings, including M-x and prefix arguments, numbered links, and buffer-style browsing. Developer quote from the web site: “To make sure Conkeror remains pure, I do not own a mouse.”
I’ve been using this on my laptop for the last few days. It is a bit unpolished. And, I find I do still miss tabbed browsing — but hardly anything else. It is extremely simple to install… so come on, you know you want to.
