As I was setting my laptop on the end table, i had my tablet on the keyboard and it must have hit some function keys or something, now the entire page is characters. I have tried running troubleshoot in safe mode, refreshed, view is set to Western... This only happens for my facebook page which is what it was on when it happened, all other pages are fine and I can open facebook in MS Edge without a problem. I even cleared my cache, uninstalled and reinstalled a fresh download of Firefox after restarting the computer. It still does the same thing! Help Please!
