I am using Thunderbird 78.0 32-bit. Everything worked fine yesterday. My Thunderbird was updated to 78.0 last night. This morning when I open an email in a new tab, the subject line is there but the email is blank. If I open an email in a new window, it opens properly. If I use T-bird in safe mode, emails display properly in a new tab. I have no add-ons, and the issue still occurs if I turn off my security software. Windows 10 v1909 updates were installed earlier this week, but I think this is an issue with 78.0 (updated last night).

sfhowes - your reply on Mozillazine support page worked. Thanks again. "If it works in safe mode, try this: start in safe mode, check 'Reset toolbars and controls', click 'Make changes and restart'."
