By the way there is an add-on you can use with Thunderbird called "Remove duplicate messages" you can use to help you clean up after such a re-download of many duplicate messages.
Just another thought - Thunderbird works strictly according to the POP3 protocol which controls the responsibilities and actions of a mail client and a mail server. In the POP3 protocol the only status of a message on the server is it exists or it does not. There is no recognition in POP3 of the read or unread state of the message on the server. So it needs a bit of understanding of what the Webmail extensions are doing/changing etc when they making reference to "read" and "unread" messages on a Webmail service.
