Firefox renders some pages extremely slowly on FreeBSD

[Nick Fishman]

I've noticed that there are some pages that cause Firefox to slow down
incredibly. Typical problems include a major increase in response time
(from a few milliseconds to several seconds). It becomes impossible to
scroll or use the browser with other tabs while these pages are loaded.
Here are a few pages that I've noticed the problem with:

http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=68847741
http://profile.myspace.com/index.cfm?fuseaction=user.viewprofile&friendid=33169214

Unwieldy HTML aside, both of these pages deal heavily with image
transparency. That could be the issue, though I'm not sure. Curiously,
these pages cause no problems with Konqueror on the same machine. They
also work fine using Firefox on Windows.

Has anyone experienced similar issues? Thanks,

Nick
