This machine, my laptop and droid have separate gmail accounts. The other win 10 pc has a different email Here is the error: An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Background info: Google issued a notice that it was removing unused gmail addresses, but ALL OF MINE ARE IN USE. I am getting the same message on my other win10 pc today.
