Download Vimium-FF for Firefox. The Hacker's Browser. Vimium provides keyboard shortcuts for navigation and control in the spirit of Vim. This is a port of the popular Chrome extension to Firefox. Most stuff works, but the port to Firefox remains a work in progress.
Very useful and pleasant to use. You almost don’t have to move your fingers out of the keyboard with this extension.
this is my dream extension! thank you for sharing :)
