I am writing because Youtube was having some issues with adblock plus the last few days. The only advice the adblock plus forum could offer was to reset Firefox and reinstall the add-on, which I did, but it doesn't seem to have fixed the problem. In fact, it made it worse, as now I cannot get videos to play on it at all. And as it is, I didn't know I could backup my old preferences and the like and thus did not know to backup my preferences and the like before I did the reset, and I have forgotten how to readjust the way I had my Firefox set up. (More information on how it looked can be found at https://support.mozilla.org/en-US/questions/1023414 <----This article, complete with pictures of how it used to look on the left. As such, I feel like I've done something remarkably stupid. How do I undo a reset of Firefox? Or at least regain the old setup as much as possible so that I can watch Youtube again.
