The error I'm receiving on Firefox Aurora 10.0a2 (2011-11-27) is:

VKLog is not defined http://switchcam.com/assets/js/utils/facebook.js?ver=2011112... Line 81

VKLog.dlog("checkSessionStatus()");

It does seem to work with Adblock disabled, so I'd guess a subscription is blocking something essential.

Interesting, thanks for poking around! I don't think we use anything dodgy (except maybe Facebook libraries) but I'll see if I can set up that configuration and debug it. Really appreciate you taking the time to write this up. Cheers, Chris

I'm having the same problem. I think it's a bad idea to use Facebook libraries for critical functionality. A lot of people (myself included) block Facebook resources from loading on external sites to decrease their ability to track user activity.

Thank you! I think you must be right about the adblock thing. We once had a similar thing with a Chrome plugin that borked things. We'll look into it; thanks again.

For me it was Adblock blocking your http://switchcam.com/assets/js/utils/logging.js script. Things work fine once I let that script load.

It does it too when on uses ClickToFlash/ClickToPlugin Safari extension. Selecting Flash in the source selector makes it work.
