After the logo change, Yahoo! made another re-design. This time the mailbox have changed! I think is the third interface change on the last years. Lot of petitions are open to bring back the old design. If you are also not satisfied with the new Yahoo! design, there is a trick how to roll back.
Over the Settings menu, select Preference.
In Preferences, look for the “Viewing email -> Mail version” setting. Change it to Basic.
If you have change your mind there is also a button to: Switch to the newest Yahoo! Mail.
I am trying to go back to the old yahoo design. Unfortunately when I click on Basic, nothing happens.
thx
What browser are you using?
Firefox. Managed to chanae it to basic, and save it. But after I leave mail and reopen, it has gone back to the new version again.
