A quick heads-up regarding a soon-to-be Firefox compatibility issue:
I've been doing some testing with the videobridge and the latest libjitsi, which enforces the DTLS fingerprint check (videobridge issue #78). I've found that this breaks compatibility with Firefox. It seems that Firefox is sending a self-signed certificate that uses a SHA-1 hash, but sends a SHA-256 fingerprint in the SDP. This falls foul of the code in verifyAndValidateCertificate(), which expects the same hash function to be used in both cases.
