Ok, so I just downloaded Mozilla Firefox and Thunderbird (latest versions) the other day onto my primary PC. Everything installed fine and both programs seem to work great.

The problem is that every time I receive new e-mail through Thunderbird (I use Comcast POP3), it will pop-up and tell me, "Received new message(s) in Local Folder," or something like that; however, I can't find the messages anywhere!

I even did a message search by date, and it says there are no messages that match that criteria. I also checked the 'Trash' and other folders, but no luck.

Outlook Express receives and shows them fine.

Any ideas? =(

Well, just in case anyone is interested, I think I figured it out. Apparently I was letting Outlook Express still download the messages and Thunderbird was not able to retrieve duplicates since of course they were already send from the Comcast server.

Ah well.
