Steps to reproduce:

I added following feed to my RSS feed account in Thunderbird.
https://weka.pwr.edu.pl/rss/pl/5.xml

Actual results:

After some time I got duplicated items in this feed.
See screenshot.

As I understand this feed serves only "https" links, but in my feed I get 2 versions of each message, one for "http" and one for "https".

On screenshot you can see, that there are actually three copies of each message. Two of them are "http" and third one is "https" (although I can't reproduce "http" duplication after resubscribing, so I am not sure what is going on).

I searched the internet and I found http://forums.mozillazine.org/viewtopic.php?p=13360829#p13360829, which I checked and it seems to be the answer, but when I look at source of items in my feed, the "http" ones had the same "Message-Id". "https" differed only by "s" in url part of "Message-Id".

Expected results:

I shouldn't get duplicated items in my RSS feed.

Other clients like, QuiteRSS or Nice Feed for Android don't give duplicated items.

Component: Untriaged → Feed Reader
Product: Thunderbird → MailNews Core

Recently there were some new items in feed.
Here is a screenshot
As you can see these items are duplicated too

https://weka.pwr.edu.pl/rss/pl/5.xml works for me. And there are no duplicates.
But the feed ends around the date you created this bug report.
