I want the old format yahoo mail back?

try this link http://us.mc598.mail.yahoo.com/mc/launch this should give you classic mail version thanks to those more knowledgeable folks that come up with the tech we need the classic homepage link is http://ipv4.yahoo.com/

There is NO LINK available that will take you back to Classic/Original Yahoo Mail and continue to work PERMANENTLY. Here is a solution that DOES work and works very well. I have multiple Yahoo accounts and I have used this method with each of them with great success..... There is a way that just involves a few mouse clicks. It sounds like you have Beta Mail (double yuck) and want to go back to the ORIGINAL Yahoo Mail. I have found a way to do just that For Internet Explorer: Go to Tools/Internet Options/Security, go to "custom level”....scroll down to "Active Scripting". Click on “Disable”. Hit OK. Refresh the page while you are still signed into Yahoo Mail to switch back. Be sure to go back in the same way and “Enable” Active Scripting again...(and NO it won't revert to the Beta versions of Yahoo Mail) For Safari: Open Settings, Click on Preferences, Click Security, Uncheck “Enable Java” and then Enable JavaScript For Firefox: Open Tools, Options, Content, Click “Disable JavaScript”. Hit f5 to refresh the page while you are still in Yahoo Mail to switch back. In Options, click “Permanent” to stay in the original version. Do not click the “One Time” option. Voila! You now have Original Yahoo Mail back.
