SpeedyFox is a small freeware utility that speeds up your Firefox load time by optimizing the profile databases. The devs claim up to 3 times speed increase, and I’ve got to say Firefox certainly seemed a lot faster on boot up when I tried. Or is that a placebo effect? Anyhoo, well worth a try.
It seems unbelievable but after you optimize your Firefox with this tool, you will get a fresh newly-installed feel because the speed indeed gets considerably faster. You will get up 3 times faster startup speed, browsing history will become faster, and performing operations with cookies will be quicker than before.
