Tried it on both and on both it gave the warning that it was not trusted.

I looked all over both Mozilla's and Comodo's site and can't find anything but other people having the same issue all the sudden. Most of them point to the 'server being misconfigured', but nothing more to go on than that, whatever that means.

The only thing I think is that the OU is missing and so is the organization from the cert when you examine it. Maybe I can get those filled out tomorrow by Comodo and that would do it? That's what I've come to. I think everything is installed correctly, though.
