Ubuntu 13.04--Firefox bug

[hoboy]

Since I have upgrade ubuntu 12.04 to ubuntu 13.04, my yahoo email has stop working.
In the sence that when I open my mail box the inbox is pull every 3-4 sesonds, that mean it checks for for new email every 3-5 sesonds.
This is a new bug because this email has worked fine under 12.04.
This problem only occured in Firefox, not in Opera, not in Chromium browser.

if anybody has the same problem I did found this on the net
sudo apt-get remove unity-webapps-yahoomail
that has solved my problem.

This solved my problem. I tried reinstalling, and the problem returned. I guess that webapp doesn't quite work right yet!
