I'm unable to open my Yahoomail with the Firefox web browser. I've already tried reinstalling and Yahoomail works fine in other browsers.

I'm able to access the website and load the Mail "home page" but once i enter my login information and click "login" an error message appears on the screen "404: Not Found". I can access yahoo mail in other browsers; just not Firefox.

I've already tried the following: deleting cookies; deleting temp. files; reinstalling firefox; upgrading firefox; checking your website for information but no one seems to have given a solution and this apparently has been a problem with firefox for awhile.

I sure hate not being able to use Mozilla Firefox because I can not view my AT&T Yahoo e-mails. I get 404 Not Found and nginx/0.6.32. Anyone out there including Firefox chat personnel that can "fix/cure" this problem? All the other browsers have NO PROBLEM. I even had AT&T ConnTech personnel work on the problem. No solution!!! Gene C.

P. S. I think Mozilla Firefox is the best but now NO AT&T Yahoo e-mail.

I followed all of the steps TO THE LETTER with so much hope and it didn't work lol This really sucks too cuz i love Firefox; i left IE to start using it. But one of the first things i do everyday is check my email..Firefox isn't letting me.

I'm still getting the same message: "404 Not Found/nginx/0.6.32"...

Any other suggestions?

Yes, AT&T Yahoo e-mail works on the other browser such as Safari, Opera, Chrome, and Internet Explorer. Even going to Yahoo's web site let's you view their @yahoo e-mail address that I have but not Mozilla Firefox. Anyone got an e-mail and/or telephone number to get this on the major bug list?

I had another session yesterday with AT&T Connect Tech online hardware and software support. Well he worked on the problem for over two hours and even loaded an older version of Mozilla Firefox. Result was the same 404 Not Found nginx/0.6.32 every time I go to AT&T's home web site. I can see about five e-mails (who they are from and the subject line BEFORE going to the mail button to sign on but once giving them your e-mail address and password, SAME results using Mozilla Firefox.

I tried the suggestion given but also get the same results. This is a major bug either at AT&T and/or Firefox.

Found out that AMALAHI and I had same solution, deleted Anti Phishing Domain... Now my mail works fine. Apparently while I downloaded free Chistmas animated screensavers ( for Mom (visiting)) this was included and it was Panda when I clicked on support info. Restarted Mozilla firefox newest version and I can read my old Yahoo mail fine. I access mail from My!Yahoo. I place hand on mail then click first one and I am still in old reliable version. I have new mail in another login elsewhere and do not care for "improved" version.
