Thunderbird 147 release install gives error "XML-parsefout: ongedefinieerde entiteit"

Hallo Mozilla Thunderbird support I was executing this manual : https://support.mozilla.org/nl/kb/thunderbird-installeren-linux#w_thunderbird-handmatig-installeren-voor-een-specifiek-releasekanaal-voor-gevorderde-gebruikers. Reason : I have installed Linux Mint 22.3 Cinnamon which came with Thunderbird 140 ers. My mail has been transferred from a computer (with problems), which used ? a younger ? version !? I use Thunderbird for many years, with profile manager and 6 profiles in it. At the moment I cannot work with my mail. Which is bad for me ... >:-| Starting thunderbird with thunderbird -P "You have launched an older version of Thunderbird" A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again. I did worked al those instructions, which went good. Almost done I dont get the launcher on the desktop Most important is this error popping up in a yellow box This is the error XML-parsefout: ongedefinieerde entiteit Locatie: chrome://messenger/content/messenger.xhtml Regelnummer 48, kolom 1: <html id="messengerWindow" xmlns="http://www.w3.org/1999/xhtml" ^ Please help Thanks in advance Hans Bollen hans.bollen@linuxzob.nl https://www.linuxzob.nl/wiki https://www.linuxzob.nl/wiki/doku.php?id=linux_internet:thunderbird#thunderbird_mail_-_verjongen
