Just installed 13.04 with built-in Firefox 20.0. Strangely enough in Yahoo Mail I cannot view contents of any mail folder except Inbox. Any other folder (Sent, Trash, etc) when clicked won't open but for a fraction of a second, then disappear, and contents of Inbox are shown again. And it keeps checking for new mail every 5 seconds!

I have same problem. Linux mint 14 Nadia, is just fine with yahoo mail, only in ubuntu 13.04. It is only yahoo for me, as gmail is fine. Fond a solution here: http://ubuntuforums.org/showthread.php?t=2139807&p=12623430. I opened synaptics and marked for full removal, but synaptics crashed. So I opened up in terminal and typed:
And everything works again! I do not know what the webaps does for me, I read that I could reinstall it and it would work, but for now, I will leave it uninstalled and enjoy my yahoo. mail! Thank you Jenks 141 for leading me to the solution!
