Everything was completely fine, then I left for a week to go on vacation. After I came back I tried to log into youtube, and I got a 400 error. After the failed attempt to log in, now I can't go to any pages on any site, including youtube which I was just on. If I try to load a page, it just stops instantly. If it goes past that, it just says that firefox can't connect to that server. I went into my cache and made sure that cookies were all cleared, and even went into my firefox profile to see if there was anything and there isn't. I tried restarting firefox, and my computer, neither helped. Firefox is completely bricked right now and I have no idea why. I hate that I even had to boot up chrome to type this out.
