I looked into this a bit. The site seems to be ilooping in a script doing top.document.location, document.referrer, top.document.location.document.referrer, and window.parent.document.location. FF shows a single error "initCookie is not defined". Chrome shows the same error but also a bunch of security errors (accessing cross-domain window) that we don't report. This would seem to finger something in our DOM/XPConnect logic so I'm tentatively booting over to XPConnect. It would be really helpful to get a regressing cset to take this bug further.

Is that the initial compartments landing?
Sure looks like it, yes.
This seems to WFM now.
Either the page changed or the bug is fixed in current builds. I can confirm that it works with Firefox15.0.1
