chess.com email problems with firefox

When I go to chess.com using firefox I see that I have new emails but when I click on the email icon there is nothing visible in the Inbox.

When I do the same using Internet Explorer there is no problem, I see the new emails.

Any advice? (except "use IE")

I had this problem before, but now it seems to be ok.  I'm not sure why it is working now, but not before, sorry!  Try reporting it as a bug.

try clicking on the INBOX folder on the left menu of the email screen.

I did. Nothing happens.

With IE I see: Inbox (1)

And also the page Welcome to your Start Page

With Firefox I see: Inbox

And not the page Welcome to your Start Page

I managed now to see the Start Page by clicking on the Chess.com folder (top of the left menu).

From the Start Page I can click on the email and open it.

Still I clicking on the Inbox icon does not work.

using ff 3.05 and it works fine
