Wow, as a emacs user, I think the "conkeror" browser is better : it's entirely based on firefox, but uses javascript as its extension languge. Just like Emacs, kernel + extension , instead of lightweight or 'unix philosophy'
It uses JavaScript as extension language, just like… Firefox? Impressive!
I'm always annoyed when people don't realize that Firefox is basically Emacs: the actual engine is called XULRunner and has a renderer called Gecko and supports stuff like sockets. Firefox is on top of it, implemented basically in JavaScript and the UIs are described by the XUL format which can be compared to GTK+'s Glade-files, Qt's UI-files or XAML.
