Every thing was alright with Firefox and YouTube, but when I went on YouTube this morning Firefox kept crashing when I tried watching vids? it either plays but the vid & audio is very bitty, or I get a black vid screen! or a grey screen with white exclamation mark in the middle? I tried resetting Firefox, but this didn't help, or made things worse! I also updated to Firefox 34.0 but still it wont play videos!

Hi AVITYourway, Thank you for your question, I understand that resetting Firefox did not reset the error that you are receiving. However, can you please check if you are viewing the video in HD? Or if this also happens in Safe Mode?
