Rated 1 out of 5 stars

Downloaded latest version 1.0.0.13 and it doesn't notify me of new mail. I even click on it to have it check and it says I have no new messages even though I do. Uninstalled it.

This review is for a previous version of the add-on (1.0.0.13). 

The extension gets the "new" mail count from Yahoo. "New" mail is mail that has been received since last visiting the Yahoo Mail web page.

If it isn't working, then check http://www.yahoo.com when you think you have new mail. If that doesn't indicate you have new mail, then the extension won't either.

If you do have new mail and Yahoo says you don't, you'll need to contact Yahoo to have that fixed.
