Recently, I noticed when I click on some buttons like compose, delete, move, spam, nothing happens. When I use Internet Explorer instead of Firefox, every button in Yahoo email works. Actual results: I googled this problem and found a workaround for Firefox. In Yahoo email page, I clicked on "help", then "settings", then "viewing email" then "basic" then "save". The buttons work but I don't like this basic setting. Expected results: Obviously, the fault lies in Firefox, not Yahoo email because it works fine in Internet Explorer. Please let me know if you are working on this problem and resolve it early. Thank you.
