I have used Firefox for years and love it but have always been a little miffed with how slow it loads 1st time before it's cached compared with IE.
Just found a great tip on how to speed it up and also this has increased surfing page loading.
Right click on any Firefox short cut/Properties/Find target and right click on the firefox.exe/Properties/Compatibility and change to run in Win 2000 mode.
If it doesn't work for you just go back to the default.
