I can log-in to my e-mail account using FireFox "Private Browser" and all other browsers, but not from Firefox's normal browser. I receive a message form ATT/Yahoo that something is wrong with my internet of WiFi.

I have been struggling with this off and on for several months. But all of a sudden when I went to log-in the normal FF browser so I could send screen shots, I was able to log-in. Within the last hour I couldn't log-in and have did nothing but read community questions and answers. This happening out of the has destroyed my efficiency.

Any ideas?

You will be very surprised to learn one of your addons may be doing this. Specifically the DuckDuckGo Privacy Essentials addon. It was reported disabling this addon allowed people to login into their AT&T Yahoo emails without errors. It seemed to be a popular problem from Jan to February of this year.

To disable or remove this addon: Disable or remove Add-ons

I would uninstall this addon. You don't really need it.
