Put Firefox on Steroids!
Dewd! If you use Firefox, ya gotta try this!
It makes Firefox FLY on the net. When you click on the link to install, you will have to allow the pop-up from the web-site, then click it again. Get out of Firefox, back in… and watch it FLY!
i think that it does the same thing as doing about:config and changing the options in there, it just adds a timer and makes it easier for the masses
