When I just recently Uninstalled it, my computer monitors now work fine without desyncing from my PC itself. This has never happened before and I even went into my computer programs to determine any other factors. Right now in stress testing, I just used Microsoft Edge to go on the internet and even went to youtube to play a few videos when with Firefox, I would get as far as maybe the front page and my two monitors would then desync from the PC. Everything seems fine now as I'm even attempting a installed game to possibly be a factor as well but so far in being on the computer now for almost 30 minutes without FireFox, not once has it desynced. I don't want to stop using Firefox as it has been my primary browser since back in 2006, but I can't use it if this becomes a problem. If I were to install it back again, would I get the same problem or would it be fixed?
