Thank, but that doesn't seem to be doing anything, thunderbird doesn't even bother recreating a new one. I didn't find anything else useful in that folder that would clear the content without completely erasing the feed.

It works exactly as designed. Users are very adamant about not wanting duplicates and this use case only comes up in testing situations.

If you want to test, note that you can do so by creating a local xml feed file, with a tweak, see here: https://bugzilla.mozilla.org/show_bug.cgi?id=1167850

Also, make sure to carefully read the guide: https://support.mozilla.org/en-US/kb/how-subscribe-news-feeds-and-blogs

Hopefully you are creating an Atom spec feed and making sure it validates, not reusing quid/id, etc.

That will ensure all feeds in the account get duplicates. There is no reason to recommend deleting system files for operations that should be done within the application. Deleting the feed itself ensures its own data is cleaned up.

The guide links to a detailed post about how dupes in Tb feeds work.

Well how do I get one feed to redownload. I really have not got the time to rad that article. I skimmed it but I really see nothing useful at all to force a redownload of the feed.
