Thunderbird ver. 78.4.3 (64-bit) Mac OS ver 11.0.1 Big Sur

Thunderbird become lag after upgrade the mac os to 11.0.1

Scroll the mouse, the "Subject Panel" moving very lag

Dear All, I received an update and installed it. Afterwards my TB does start but no main window appears. On the menu bar I can see a beach ball. I search a little bit and installed the latest version that I could find, which seems to be 78.6.0.

Still no change and not able to read my emails, since there is no main window.

I tries also to start the application with "option safe mode" and de-activated the add-ons and rest of the menu bar...no success so far.

Any other hint and tip that you share with me, please ?

Thanks HS
