Greetings All, Have Googled this to no avail. Win 7 Home Premium SP1. When trying to access any site on FF (Ver. 62.0.3) getting error
Unexpected response from server
Firefox doesn’t know how to communicate with the server.
Check to make sure your system has the Personal Security Manager installed.
This might be due to a non-standard configuration on the server.
Internet explorer working fine on this computer. Have tried "Refresh Firefox" and "Restart with add-ons disabled" In their troubleshooting wizard. I Have to avoid un-install - re-install as I am trying to help an elderly neighbor and she does not have ANY ! of her passwords written down. Any thoughts suggestions greatly appreciated. Cheers !
