Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

Updated to 102.0.1 (universal build running on M1 OSX 12.4).

Actual results:

Noticed that some folders display message threads instead of messages sorted by dates despite mail.strict_threading set to true.

Expected results:

Message sorted according to dates when received. This error cannot be reproduced with SeaMonkey 2.53.12.

This issue seems to be consistent across platforms as it can be reproduced on a Win10 installation as well.

Noticed that some folders display message threads instead of messages sorted by dates despite mail.strict_threading set to true.

That is not the setting for threaded or not.
Threaded is now the default for new folders.

With that info, is your issue resolved?

No, it's not.

If this is not the correct parameter anymore, then what is? Ie, what do I have to do to disable all threading for all folders in TB?

Per Magnus' comment from above, the documentation at https://wiki.mozilla.org/MailNews:Message_Threading#mail.strict_threading is misleading and needs correction based on the answer of my question.

The right pref is mailnews.default_view_flags, which is what new folders are inited with. (It won't apply to folders that have a view mode set.)

Unfortunately, setting this variable to 0 (as indicated in https://bugzilla.mozilla.org/show_bug.cgi?id=86845#c74 ) doesn't seem to have any effect.
Has this passed regression Q/A ok?

Of course it has an effect, that's why you're now seeing threading by default (since bug 1764842 where we changed the default for that pref)

Why doesn't setting this to 0 have any effect then?

Only for new folders, since the setting is saved per folder. Folders are only initialized with this pref, but after that the user may have changed it so there is no default.

In that case: How do I change this view for all existing folders?

I think you can't. Bug 574986.
