Yes, that page is broken for me as well, in the same ways as you
describe.

As I noted in my other reply just now, this behavior seems to have a
known cause, the etiology of which is some combination of xorg.conf
settings, video driver and image characteristics. 

Contrary to your initial comments above, I do think that these bug
reports are relevant to what we are observing, especially since the
problem is consistent with not being present in FF2, which is what
others have also observed. The initial preception was that this was a
major regression of sorts in FF3, but it now appears to be known that
there are other factors at play.
