fx4 issue?

[primexx]

Firefox 4 beta 7 (candidate)
NoScript 2.0.4



When i go to facebook, or when i do a search in google (type something then hit enter or click search button), an invisible iframe gets blocked. looks like iframe URL is the same as the main website. I have both "facebook.com" and "google.ca" whitelisted. iframes are blocked for untrusted sites, but the "apply restrictions to trusted sites too" checkbox is not checked.

The same settings had no problems on Fx3.6

Possibly a problem arising from Fx4 changes or is there perhaps a different setting i've overlooked?

Thanks!

It's a known Fx4 bug, which swill be fixed by Mozilla before final release (hopefully before next beta) because it has also security implications.
