How can 5 lines of html crash windows?

I was using Firefox (not sure the version) on XP home and the first one came up after the computer hang for about 15-20 seconds and then the second one forced a reboot but I didn't get a blue screen , I havn't seen one in a while...

Firefox 1.0.4 on Fedora Core 4 opened them fine without even slowing down though...

Neither did anything to my FF 1.06 on WinXP Pro.

i am guessing my problem with FF are extensions.... since i have lots of them installed.
