If you are a die-hard Vim fan and haven’t heard of Vimperator already, here’s great news: You can control your web browser using the keyboard without the need to touch your mouse just like in Vim.
Vimperator is a Firefox extension that creates a Vim-like environment in your browser. It removes all clutter including the menu bar, tool bar and bookmarks bar. However if you want, you can bring them up again using a simple command. Navigating the pages are same as in Vim, use hjkl and what-not. The list of commands you can use is enormous, but thankfully Vimperator has a great documentation as well. Just type :help and hit Enter to view the help.
You can build aliases, map keystrokes, etc in a separate configuration file named .vimperatorrc. There are also dozens of plugins available.
It takes some time to get used to the command-only interface, but once you are through you will know that it’s worth the effort.
Take a look at the minimal look of Firefox once Vimperator is installed:
