Even if you don't do anything this makes seems to make Mozilla really slow 
(100% cpu usage).

I'm seeing it too althoug it's not that drastic. Linux build 20020121, Duron 750Mhz, 512M Ram. CPU usage fluctuates between 20-30% while thatpage is open and I'm not doing anyting. Going toany other page drops the load back to usual (near 3%).Additionally, there is something weird going in withthe back/forward buttons on that page. 1) clicking back button doesn't do anything2) picking a link from the dropdown menu by the backbutton does work.3) going to another page and then clicking "back"from there displays an empty page.

Something ate my linefeeds, so I'll post again. Hopefully this one
is easier for the eyes. Sorry for the spam.

Is this one related to bug 96633?

The page in question is doing some funky JS things; I end up with 4 of it's
pages in the history (thus the inability to use Back; it just goes forward again
immediately).
