Hey, First, Firefox you make it way to hard to find where to ask a question!!! Second, some app or program is causing Firefox to keep YouTube from opening videos automatically? I know the solution is to reset Firefox and it works. But, I would like to know what is causing this to happen in the first place? It is very annoying and something is doing this without my permission!!! I want to know hat it is so that it doesn't keep happening as it is. I want YouTube videos to play automatically so that I don't have to keep clicking to start each video in a play list or just to get videos to start when I fist open YouTube. I don't ave time for such an annoying thing! I don't know if it's Firefox or an app or a program but I would really lie to know what is doing this so that I can delete it from my computer! I would like to keep using Firefox but will have to change if I have to keep dealing with this. Anyone? John
