Browser freezes after search results finish loading

[Matthew Cline]

When doing a search with Bugzilla, dmoz.org, or Google (but not AltaVista),
the browser responds fine while the results page is still loading, but once
it's completely loaded, it freezes for about 30 second, while Mozilla's
CPU usage spikes, and then it goes back to normal.  I'm sure that the
bug for this must be somewhere in Bugzilla, but I haven't been able to find
it.

I'm using Linux build 2001091908, but this problem has been there for 
several weeks.

Thanks in advance.
