Why after Windows 10 Update Firefox won't connect to internet but Edge connects

more options

I have tried repairing, reinstalling, disabling windows firewall, resetting tcp/ip and still no luck. I have also done some of the command prompts in firefox too. I looked into my antivirus Bitdefender and don't see any issues either. I love FIREFOX and want to use it! Please give me suggestions. I even started in safe mode.

I have just uninstalled my antivirus Bitdefender for a separate issue but will wait a few days before installing it.
