Thunderbird Beta and Release: External GnuPG Keys Not Working with GnuPG 2.5.x (locked duplicate)

DEUTSCH (English see below):

Hallo zudammen,

Konfiguration: - Window11 25H2 (aktuell) - Thunderbird Beta-6 (BuildID=20260213180051) - gpg2.5.17 (Gpg4Win 5.0.1); siehe auch: <https://www.gpg4win.de/>

Der bisherige und standarmärige Installationspfad von "Gpg4Win": "C:\Progam Diles (x86)\Gpg4Win\" wurde softwareseitig auf: "C:\Progam Diles\Gpg4Win\" geändert!

Bug 1967121 (Closed) => thunderbird148 --- fixed! <https://bugzilla.mozilla.org/show_bug.cgi?id=1967121>

Zur Zeit verfolge ich die Änderungen bezüglich der externen Schlüsselverwaltung in Thunderbird-Beta, da das Arbeiten mit externen Schlüsseln in der esr- und in der relesease-Version von Thunderbird seit der offiziellen Herausgabe von gpg2.5.x absolut nicht mehr möglich ist! Die geheimen Schlüssel für das Entschlüsseln und Signieren werden mit gpg2.5.x nicht mehr gefunden!

In der Schlüsselverwaltung von TB-Beta befinden sich meine öffentlichen Schlüssel und alle öffentlichen Schlüssel meiner Kommunikationspartner. Extern sind meine geheimen Schlüssel gelagert. Folgende Präferenz wurde aufgrund von gpg2.5.x hinzugefügt:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-02-25-14-35-46-df59be.png

Allerdings erscheint nach all diesen Maßnahmen die Fehlermeldung: "The secret key that's required to decrypt this message is not availlable."

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-02-25-14-36-58-d8280e.png

Mit Herausgabe von Thunderbird/148.0 (release) sind dort die gleichen Probleme mit der externen Schlüsselverwaltung zu bepbachten!

Mit Versionen gpg < 2.5 funktioniert unter Windows alles problemlos!

UNTER LINUX haben hier Änderungen an der Präferenz: "mail.openpgp.load_untested_gpgme_version" nachweislich keinerlei Auswirkungen!

Was übersehe ich?

ENGLISH:

Hello,

Configuration: - Window11 25H2 (current status) - Thunderbird Beta-6 (BuildID=20260213180051) - gpg2.5.17 (Gpg4Win 5.0.1); see also: <https://www.gpg4win.de/>

The previous and default installation path of "Gpg4Win": "C:\Program Files (x86)\Gpg4Win\" has been changed by the software to: "C:\Program Files\Gpg4Win\"!

Bug 1967121 (Closed) => thunderbird148 --- fixed! <https://bugzilla.mozilla.org/show_bug.cgi?id=1967121>

At the moment, I’m following the changes regarding external key management in Thunderbird Beta, because working with external keys in the ESR and release versions of Thunderbird has become absolutely impossible since the official release of gpg 2.5.x! The secret keys required for decryption and signing are no longer found when using gpg 2.5.x!

In Thunderbird Beta’s key manager, my public keys and all public keys of my communication partners are present. My secret keys are stored externally. The following preference was added because of gpg 2.5.x:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-02-25-14-35-46-df59be.png

However, even after all these measures, the following error message appears: **"The secret key that's required to decrypt this message is not available."**

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-02-25-14-36-58-d8280e.png

With the release of Thunderbird 148.0 (release), the same problems with external key management can be observed there as well!

With gpg versions **older than 2.5**, everything works flawlessly under Windows!

    • UNDER LINUX**, changes to the preference

"mail.openpgp.load_untested_gpgme_version" have demonstrably no effect at all!

What am I missing?

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript
   If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

Locking this thread, please continue here: [/questions/1572529]
I've been using alt+a to open new tabs in a multi account container for a long time. Recently that shortcut stopped working possibly with the update to v148 as indicated in this reddit thread.

alt+a is not listed as a shortcut in about:keyboard or in about:addons > manage extension shortcuts or in my ubuntu shortcuts nor in any software I can think of thats running. I've disabled all my add-ons except multi account containers to no avail. I can change the shortcut to another and it works fine.

Why would just that shortcut stop working? What else can I do to diagnose the problem?

Since version 149, the search box in the address-bar has a different behavior and layout. There may be cases, when this behaviour is better, but I don't get it. In my use-case, I have got to do several more clicks to select the correct search engine with every search.

How to get the old style & behaviour back:

enter: about:config in the address-bar. confirm security question. search the entry: browser.search.widget.new and set it to 'false'

No restard needed.  :-) Thank you, Firefox developers!

Would be great to have a checkbox in the settings and the option if you want your familiar solution changed. (add this at the bottom of the new select search-engine dropdown.)
