Hello Carsten, Please be so kind to carefully and completely, before you make wild assumptions.
I didn't use a pre-built version before, instead I used the packaged version as stated in my initial message. A very similar problem is described in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946193 for Firefox. Please read this bug report, hopefully you can draw some knowledge from that. I assume, that the buster versions are build before the stretch versions which makes the stretch versions being a little bit higher. Thank you for your efforts. Best regards, Robert PS: Unfortunately, the provided link didn't help me much. -------- Original Message -------- From: Carsten Schoenert <c.schoen...@t-online.de> Sent: 9 December 2019 22:09:01 CET To: Robert Pommrich <leprovokat...@gmx.de> Cc: 946...@bugs.debian.org Subject: Re: Bug#946347: Thunderbird: After dist-upgrade thunderbird thinks it is too old.

Seeing this message isn't something you can blame the Thunderbird package from Debian as you have used non packaged software on your own. https://support.mozilla.org/en-US/kb/unable-launch-older-version-profile Please adjust your local profile settings by reading the ressource I've linked above.
