Could be a Flash problem, whatever it is it affects Firefox under Win XP also.
It seems to be a java script issue- try http://www.saint-gobain.com/en/html/soc ... =1&pays=18
and click on any of the listed activities. Crashes my Firefox (under Mint - haven't tried XP) without fail.
However Firefox 3 handles the page perfectly. Roll on Firefox 3.
Things just improved a lot, loaded the JRE Firefox extension. Now wha isn't that installed automatically?
