Strangley. Putting the same code on a differnt page doesn't crash firefox. Theres something on this page which causes it to crash.

It's something to do with that page. Moving the same code to a different page works fine. The post thats causing the problem is the nested <marquee><sup> one. Removing that post stops the crash. Moving it to a different topic on the same forum it doesnt crash. It's some combination of the previous posts and that one. *updated URL to the crashing one. Previous URL was the same code on a different page... which diddn't crash.*

Was repaired on trunk between 1.9a1_2005090908 and 1.9a1_2005090921.

That page uses nested marquees, so it is basically a duplicate of bug 277208 (which is indeed fixed on trunk). *** This bug has been marked as a duplicate of 277208 ***
