Thanks for all your help! I think it is still possible as it uses activex only for sound communication only, in the manual it says that browsers aside from IE with no activex support will work, but with no sound. Also, MJPEG is supported which gives me hope. I will try it and will definately post the results here.

P.S. Just read up on Foscam website that besides ActiveX it supports "Server push mode" for Chrome and Firefox which is in fact uses no ActiveX. If I manage to set it up this weekend I will post all setings and possibly a new Widget for it.
