Right now, I'm using Explorer.... it's so slow, I'll have to shoot myself if this is the only way I can view TG!! Get me back to Firefox NOW!I feel for you Chris. What about a total deletion and re-install of firefox?
I also found this link-- don't know if anything in there will help you:
kb.mozillazine.org/Video_or_audio_doesn%27t_play
I'll check out your link Al, then I'm looking up the CEO of Mozilla and I'm calling him at his New Year's eve party to get my browswer fixed!
