I've mentioned this problem before and I wonder if anyone else has had the same and can suggest a solution:
I'm using Firefox as my browser as I have been since I joined TG but since November I can't get proper access to the TARGET videos. I can get the initial video play through on a song but then cannot get anything else to pop up. My window just stays grey.

Sometimes I get a grey window with the sound of the video playing in the background. If I reload it takes me back to the start video of the lesson. I checked in with Internet Explorer and I can access everything. I never use Explorer and don't want to change away from Firefox. I reckon the problem started after a Firefox update. Anyone help me solve this please? I'd be very grateful for any help or suggestions.
