Thunderbird 78 Mac screen is huge

user301571757577087349165058977412984109687

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?

Does it look correct if you run in safe mode (hold Option when launching TB)?

No, safe mode does nothing

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