I was having trouble with Zynga and trying to play a game on their site. They gave me advice on how to "refresh" fire fox,and after I did,I now can not go to Zynga's website,or go to Facebook. Seems Firefox has updated to 40.02,and now nothing works! I am using windows 10 .

You can try to copy the cert8.db file in the "Old Firefox Data" folder on the desktop to the current profile folder.

You can use this button to go to the current Firefox profile folder:
