I was testing a new website for a developer. I wanted to see if DNS worked correctly on various browsers. I downloaded Firefox and the test was OK. However, something happened with Yahoo and Facebook, apparently those sites think I am on another device. Where I have to log in, something with second level authentication was off, after several attempts I am now locked out. I suspect a Firefox setting is the problem. Suggestions on how to reset firefox?
