That worked ok for me without crashing. One site that I know always
crashes my browser is this one: http://www.flickr.com/photos/
Just click on any of the photos there and the new page will load up and
crash. If anyone cares I have attached the backtrace from the crash below.
This is what I have installed:

I have been bad at updating this month so I may be behind in ports and
this has already been fixed.
