What am I missing ? ?

[#1]

Sometimes watch live tv on line via
http://www.tvguide.co.uk/?systemid=3&cTime=2/12/2014%207:00:00%20PM&thisTime=&thisDay=&catColor=
Most channels are ok... just click on "watch now"... and it appears....BUT when I click on channel 4 7. all I get is a Blank Page...
http://watchlive.channel4.com/4S
so I think some software is missing  ? ?  any suggestions  ?

Watch now !  works for me ok on Firefox , have you a Adblocker ?  as this will cause problems

Yeah, I`m on FF latest version too..... others work.... I have "Ghostrey" running on FF addons... but never had any problems with it .. (apart from the "live chat"  which got sorted, and has worked since )...  I don`t have any other adblockers working ...

sorry Shutter but it defiantly sounds like a FF add on      m  problem
