All of a sudden my firefox will not load any webpages, keeps saying it is already open, and giving me a system error code saying there is a file missing. I tried going into task manager to close it manually which didn't work. I tried shutting off my laptop altogether which didn't work either. I also tried doing the refresh option after uninstalling and reinstalling and that did not work. This is the only application on my computer doing this, and it is not an internet issue because I am asking about this while using microsoft edge. I am not sure what to do and am becoming frustrated because a lot of passwords I don't have written down are attached to my firefox browser and I just don't like microsoft edge or chrome as much. I attached a photo of the error I am getting, as well as the blank webpage I get when I try to use the program. If anyone has any advice on this or knows how to fix the issue I would appreciate any help greatly. Thanks so much!
