The authors have - you just need to use the solution. This problem is caused by Yahoo. Thunderbird itself (not these extensions) decides which message to download from the server. The extension mimics a POP server and hands to Thunderbird a list of the messages on the server. Thunderbird keeps a list of the message ids on the server that it has downloaded already. It compares that list with the new up to date list and downloads the ones it has not seen before and then Thunderbird updates its list of downloaded message.
Unfortunately, Yahoo has a very unhelpful habit of regularly changing the message ids on the server (their choice - they are not providing a POP service here). So the next time the list is given to Thunderbird it appears that all the messages have never been seen before and Thunderbird downloads them all again. The Webmail Author provides the ShortId option in the Yahoo extension options. If you keep messages on the server for more than a couple of days then you need to use the ShortId option - it shortens the message ids to eliminate the part that Yahoo changes. Selecting the ShortId option has the downside that it will cause a one time re-download of the messages on the server, after that you should be safe from the re- download problem.
