Facebook will load for the login screen but regardless of who logs in the new page loads as nothing but random text and gibberish. Copy and pasted sample: ‡䯟«þ÷çËz{Aê@Z1â:g̨“pè& ±‰Žåıä_¶ðßdÚ´·U…%Eü¾@v>Ãÿc8ñØÔÂE-½=¬âŠ³›Ý|Øx. The whole page is filled with endless gibberish as listed above. However using the default windows 10 internet explorer facebook will load just fine without any problems. I have tried the following: -clearing cookies and cashe (and all history for Everything setting) -using the troubleshooting to refresh firefox -uninstalling and reinstalling firefox -attempted to run in safe mode -running with our internet security disabled (kaspersky) None of those have made any difference. What is truely puzzling is the same event occurred a day before and a clear cookies and cashe followed by a system restart fixed it over night but it returned the next day.
