Since firefox updated to ver 140, I am having issues with sign ins to various sites. example: sign in to tvguide using firefox I am told my email address is in use - choose another. sign in to tvguide with microsoft edge - everything works fine. I have been using firefox as my browser of choice. Is this upgrade causing this issue? I did not have it with the previous version. I am having similar issues with other sites SINCE this upgrade so the obvious question - did you break something adding these new features?
