Just to be sure the profile wasn't masking denied messages, I used the attached profile which explicitly allows (rather than denies) all lines starting with 'deny', comments out all 'audit deny' rules, comments out the abstractions/private-files include, and adds the dgram rules too. This is a test profile and not intended to fix the problem (ie, don't use it unless you are trying to fix the problem). Firefox still locks up with the above URL.
