Firefox Blank Screen

[lalldrin]

PFC 1.0 final is configured correctly on my server and it generally works great in all browsers, but occasionally the chat will not display in Firefox. The chat frame comes up with no contents and no errors. I have seen this happen on two different computers running Firefox now. If you restart Firefox or clear cache data and cookies it works again.

Has anyone seen this happen? This isn't a configuration issue, because the chat loads fine almost all of the time.
