The latest firefox browser for windows desktop pc broke the ability to log in to at&t (also called yahoo) email. The email works fine on microsoft edge and chrome. It worked fine on firefox until the last update.

Email didn't work for over a week, didn't work this morning, created Mozilla account - it worked for 1 day.

Now not working again. Just get a page that "something went wrong"

選擇的解決方法

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, please read: Disable or remove Add-ons

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

Threads where DuckDuckGo Essentials was identified as the problem: https://support.mozilla.org/en-US/questions/1489930#answer-1711591 https://support.mozilla.org/en-US/questions/1489722#answer-1708547

If you don't have this addon installed, try disabling the other addons you have and then go back to the AT&T Yahoo site to check your mail. Let us know if DuckDuckGo Essentials or another addon was the problem. Thanks
