Firefox becoming bloatware
Firefox is out of control, version 7.0.1 was bad, freezing all the time, with browser nonresponsive for 20-40 seconds. Just look at the size of the download, version 3.6.24 was around 7550 KB, version 8.0 nearly double at 14250 KB.
I've nearly stopped using Firefox now, and switched to Opera which is fast and responsive. Next step is to uninstall Firefox, but that will be a sad event as FF has been a good companion.
