Firefox has never played videos from GameTrailers for me and I dont understand why.
Is there some settings Im supposed to change? It runs fine on my Opera browser but not when I use FF.

Anyone got some advice?

What happens when you try to load one of the videos?

I occasionally have problems where the video skin appears but nothing plays, but refreshing usuall fixes the problem.

Nothing happens. It just says loading and thats it.

well when i couldn't watch GT vids it was because of the ad blocker, that might be it

I've had the same problem sometimes, it says loading and never advances. Other times it goes past that and looks like the video is going to play but doesn't.

As for why you have NEVER been able to watch i'm afraid i don't know. Sorry...

If you have Noscript, you should check you have scripts allowed for that page

My advice would be that you boot FF with all the plugins turned off (Start -> Programs-> Mozilla Firefox -> Mozilla Firefox (Safe Mode)), and try to watch a video from there, if you can, it's a problem with a plugin, if you can't, you've got a problem with your configuration
