I apologize for butting in, yet I also had this issue - it turned out that my Firefox profile had become corrupted. I downloaded the "Profile Manager beta 1" program after doing a Google search for "Firefox profile manager", used the program to create a new profile, made that new profile my default profile, re-opened Firefox using the new profile, re-opened Profile Manager, then copied my old profile to the new profile (using the "copy" button) - after doing this, the Upromise website worked perfectly.

The only caveat, however, is that you will need to re-install any extensions that you previously had.

I hope this helps you out.

Thank you Matthew! I must have done correctly what you said, because it's working now. I wasn't sure if I was doing it right, but I guess I did!

Can you tell me where to find the link to download the Manager? I'm not too computer savvy, so I'm a bit lost! Thank you.

Go to this website:

ftp://ftp.mozilla.org/pub/utilities/profilemanager/1.0_beta1/

Then follow Matthew's instructions.

Hope that helps!

This works for me.
