Before today, everything worked fine. Now, however, whenever I try to watch a YouTube video, Firefox crashes. The window comes up that says Firefox crashed, but clicking "Close the program" does nothing and I have to manually close Firefox from the Task Manager. What's even weirder is that YouTube keeps loading after the dialogue box comes up, and on one occasion a video even started playing while the "Firefox has encountered an error and needs to close" dialogue box was open. Strangely, I can watch videos just fine in Private mode. However, if I'm in private mode I don't get access to my recommended videos and the like, so I'd like to keep watching videos in normal mode. Please help!
