if you think firefox is slow you should probably worry about upgrading your computer. i always find it funny when someone complains that a browser is a resource hog. it's funny as hell. wtf kind of system are you running that a browser can hog your resources? firefox could use up 4GB of memory and two 2.0GHz cores and my system wouldn't even blink.
