When using Firefox I noticed that some pages weren't loading. I found it weird how no matter how I tried I couldn't get them to load. The already loaded pages were videos which were loading fine. Now nothing loads anymore. I tried to go into settings or the help menu but those weren't loading. Now I am staring at a blank window with nothing but a search bar that doesn't work. In the middle of this it came up with an error VIS something? It said that I had a missing file and said that reinstalling Firefox was the way to go. I've reinstalled Firefox already but it's done nothing but remove the error message and I still can't do anything.
