When I open Firefox, on my Windows 11 computer, it takes me to my AT&T.net/Yahoo! home page, but it shows that I need to sign in to read my email. So, I click on the sign in button, and it takes me to my AT&T sign in page, which indicates that I am *already* signed in, and shows my member ID, which is the same as my AT&T email address. So, I I click on the little arrow next to message that I am already signed in, and I'm taken to an AT&T error message page that says, "Something went wrong". It then suggests that I close the app and try it again, if I'm using the app. But, I'm not. I'm using my Windows 11 computer, and I'm trying to connect with the Firefox browser through AT&T.net/Yahoo! I've cleared all the cookies out of Firefox, and cleared temporarily cached files and such, too. But, when I try to sign in, again, I get the same darned error page. This does not happen with Chrome or with Edge. So, the problem is not with them or with my computer or with AT&T. It's a Firefox thing. This has never happened before, and Firefox is my go-to browser. I've used it every day for years. This problem happened for the first time just this morning (3/7/25). Anyone got any ideas what's wrong and how to fix it? Any help will be appreciated. Thanks, John Thomson
