Increase speed of firefox

Firefox 3 ain't fast enough for you? I am only aware of firefox 2 tweaks specifically for computer and connection types settings. I haven't seen any yet for firefox 3, I've come across a utility called Firetune @ http://www.totalidea.com/content/firetune/firetune-index.html and I haven't tested it yet, try it if you want to speed up FF some more. The good thing about this utility is you can undo the tweaks you have applied. Good luck.
