I don't like the Thunderbird version 90.0 beta updated printing ui. How can I get the old printing ui back? When firefox updated the printing ui, I was able to change the config sys to get "Print Preview" back under the File menu option. This opens the old printing UI for Firefox. But I can't figure out how to change it in Thunderbird 90.0 beta. I tried to install an older version of Thunderbird, but it wouldn't allow my saved profile data to be used, and I had to reinstall the 90.0 beta version in order to access all of my email folders. (I do pop email downloads not imap)
