Re: SOLVED: Thunderbird hangs up on printing
re-establish coredumps so we can see what's failing/going on there

That aside, https://bbs.archlinux.org/viewtopic.php … 9#p2294539 just removed xdg-desktop-portal entirely…

Re: SOLVED: Thunderbird hangs up on printing
Finally, after much scratching around elsewhere, I solved the problem.
My suspicions about distro dependencies/incompatibilities were false.
The problem lay within Thunderbird itself.
SOLUTION:
In T-bird, open "Edit/Settings/General/Config Editor" and set
"print.prefer_system_dialog" to True.
That did it. But it still leaves an unanswered question:
Why did the upgrade overwrite the original config file??
Finally. Thanks Seth for all your time, attention and effort.
I really do appreciate it. But if you ask why it took so long, maybe
my pseudonym will shed a light on the answer.

Re: SOLVED: Thunderbird hangs up on printing

Recent mozilla updates have put emphasis on preferring xdg-desktop-portal, so *maybe* the new version resets the key on first start - the package update would not write into your $HOME.
Did you for sure previously explicitly set that and not use the internal print dialog?
But many thanks for sharing at least a workaround
maybe my pseudonym will shed a light on the answer.
well, apparently not yet quite as extinct 
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I've tried several times, yesterday and today, without success
but the subject text remains unchanged.
So I edited the start of the first posting as an emergency measure!
To answer your first question.
I don't ever recall turning print.prefer_system_dialog in about:config. off,
but my memory is no longer a good as it used to be.
However, I keep handwritten notes of all main system changes.
These now run to about two hundred pages since the system was
installed on a brand new machine on 21 February 2022.
It will take time to look through all this paperwork.
But there is more.
With a search engine (Startpage) I found a listing of the
options in about:config, with explanations, on
<https://kb.mozillazine.org/About:config_entries>
That page was last edited on 11 November 2024.
I could find nothing more recent.
Interesting is that print.prefer_system_dialog is not found
in this list. Was the key-value pair in question added later??

You'll have to shorten the subject (eg. remove "failures: ")
The key is relatively new, https://bugzilla.mozilla.org/show_bug.cgi?id=1712104
Before that mozilla would have used the internal dialog.
