I have seen that this occurs around 50% of the time and I have only seen it on the one website: break.com.
Load break.com and Firefox immediately uses 100% of RAM and swap. Obviously the disk goes insane and everything slows down. The only solution is to kill that tab and try loading it again. Works fine on Chrome.
