Thunderbird 78.4.0 (64-bit) oversized in vertical size of the screen

more options

Hi, I experience huge problem with vertical size of Thunderbird running on Mac OS X Catalina 10.15.7 not showing bottom part of the app and being oversized in vertical size of the screen. I mean the vertical size of Thunderbird is much much bigger than vertical size of the screen itself no matter if on build in screen nor external monitor. Top of Thunderbird is attracted to top of the screen - can't be moved anyhow lower and can be resized to smaller size nor maximized to full screen. Even in full screen mode the bottom of Thunderbird is not visible. I tried beta Any advice?

Chosen solution

Run in safe mode (hold Option when launching TB). Any difference? If it looks correct, you may have to 'Reset toolbars & controls'.

Hi, Safe mode did the trick to see correctly full Thunderbird window. Finally I had to disable all addons and enable them again manually. Don't know which was bad but now I have all of them back and working. Thanks a lot!
