TB should start and execute the set filters.

I've never seen such a thing.
Have you Magnus?

What is Magnus?
I'm using Win10 pro 1909 on a intel-core-i7 machine with 32gb RAM and just installed Thunderbird the first time some days ago. Version 68.9.0 in 64bit.
I used only the online mail account from my provider, since there is no mail program fitting my needs. Now, I'm trying to use TB, since MS Outlook worked pretty fine for me in my last company.

Nope. I think the only explanation would be that you have some add-on installed that adds this filter.

Group: mail-core-security

No add-on installed

Hmm, I notice this: https://searchfox.org/comm-central/rev/761836864c9b6159a666a5dbe4a61d8b3caf3e16/mailnews/base/util/nsMsgIncomingServer.cpp#1838 - so it's indeed something created by Thunderbird. I don't know how it ended up there though.

The commented part of the code section seems to be wrong:
Lines 1835 to 1838:

// this is a temporary, internal mozilla filter
// it will not show up in the UI, it will not be written to disk
NS_NAMED_LITERAL_STRING(internalReturnReceiptFilterName,
"mozilla-temporary-internal-MDN-receipt-filter");

Hope this can be fixed.

I've created the filter called Blacklist, added some filters in it and executed it.
Today and yesterday at startup of TB, this error came up and all Inbox-mails were moved into trash folder. Pretty weird..

bug is still on.

This is still occurring in Thunderbird 91.10.0. I suddenly had new rules created for ALL accounts (that I've had for a decade) that added SpamAssassinYes and mozilla-temporary-internal-MDN-receipt-filter as two new filters at the top of the filters for all accounts. This has broken moving read:receipts to the sent folder and has caused a significant percentage of legitimate mail to be delivered to the junk folder. It has also caused messages to be misclassified and moved to unrelated folders for the account causing important and time sensitive e-mails to be missed.
