First there was a Navigator, then there was an Explorer. Later it was time for a Konqueror. Now it’s time for an Imperator, the VIMperator :)
That’s the welcome message at vimperator.mozdev.org. Vimpreator is a plugin for firefox, that lets you control your browser like vim.
This plugin is a extension to firefox, if you like vim. You can browse a HTML-Page like you would browse text files in your favorite editor. Have a look at the available commands and try it yourself.
