Upgraded to 78, I cannot log in to one of my email accounts
I upgraded from thunderbird 68.5 to the newest 78, but now I cannot log in to one of my email accounts. I would like to reinstall version 68, the most recent version being 68.12.1 Where do I find the file to install that version? It is in the archives, but I'm not skilled enough to get the installation files from there.
