Vimperator is the bee's knees if you don't have a god-tier mouse, or if you just don't like using the mouse. I was attempting to use my girlfriend's laptop the other day (I was helping her with a paper) and when I opened firefox, I felt so silly clicking in the address bar and having to use that clumsy touchpad to navigate. I smiled when I got back to my laptop, opened Iceweasel, and never touched my mouse a single time as I jumped from page to page, from link to link, singing happily all the way.
