I have an iMac running Catalina and Thunderbird 78. For some reason when I open my mail, the entire Thunderbird screen is HUGE. I have changed font, but that does nothing. How can I reduce the size of the whole screen?

Help./Troubleshooting, about:profiles, create a new profile. Does it still open too large?
