Even though I check the "Keep me signed in" check-box, when I close Firefox and then re-open it, I have to sign in again. I do not have this issue with Yahoo or Gmail. I have tried clearing all cookies and cash with no success.

Also, auto-fill only works once I type the first letter of my username...at the very least, since I only have a single auto-fill entry for this site, it would be nice if it auto-filled my username and password and all I had to do is click "Sign In." Alternatively, if I click on the username field, it should pop up with the available form data...I shouldn't even have to touch my keyboard unless the suggested form data is incorrect (like if I had made a mistake on a previous login attempt or something...)
