Did the update duplicate feed messages?

Checking here so see if anyone else experienced this with the recent update and to see if we should open a bug on it.

I have two separate profiles. Thunderbird updated to 78.2.0 (32-bit, Win10) yesterday when I opened my work profile. Today when I opened my personal profile (first time since the update yesterday) many of my feeds have duplicated all the messages past a given date. Presumably, the messages downloaded much earlier that are no longer on the feed were not duplicated.

Some of the feeds were not perturbed at all. I assume this is due to different feed type (e.g. Atom vs rss?). I can provide more details on the behavior of specific feeds, but that probably belongs in a bug report instead.

Did anyone else experience this? Or did anyone else here weather the update who uses the Feeds feature and not experience this problem?


PS: I've read this SO answer, but I do not think it is related since it was an update to *Thunderbird*, not an update to the various feeds that caused the duplication.

I've been seeing this for several years. I'm not seeing a matching bug report in https://mzl.la/2Ew2qF7

Thanks for the links Wayne! That second one is very similar. One notable difference is that this user claims to have been experiencing consistent duplications since the update (to 31.0). The resolution seems to be dependent on the RSS feed not having properly maintained <guid>. I looked over my feeds that were duplicating and most of them are well maintained Atom or RSS feeds (e.g. 1, 2).

I looked at the source for several of my duplicates and the only difference was the "Received: by localhost;" timestamp. Everything else was identical in the header and body.

Interestingly, the feeditems.rdf mentioned in this post no longer exists. I think it's successor is a feeditems.json in '...\Roaming\Thunderbird\Profiles\{profile-folder}\Mail\Feeds'. I cannot find any duplicates in that json file.

There is only one feed (link) which does not have a bunch of duplicated messages. Maybe because the site is dead and the feed has probably not changed at all since the update?
