Newly installed Thunderbird 78.1.1 on Catalina very slow in all actions all the time

I've Thunderbird 78.1.1 on a Macbook Pro running Catalina 10.15.6. While my Mac is v fast, Thunderbird is extremely slow in all actions - reading emails, replying, even clicking on a folder brings up the blue wheel. I've only added 3 of my email accounts as of now, 2 of which are very new with v few emails. I've NO add-ons currently. I'm wondering if I should just uninstall it. What I've tried till now: 1) Removed indexing 2) Deleted .msf files & reopened & compacted folders again (automatic compacting is on) 3) Added Thunderbird to the list of anti-virus exclusions 4) Set gfx.direct2d.disabled to true and layers.acceleration.disabled to true. 5) Proxies - use system proxy settings 6) Tried running it in safe mode 7) Deleted caches from the OS & restarted

Any advice?

If you are still seeing slowness when using version 78.4.0, please post about your current situation.

Hi, I'm still seeing the same issues using version 78.4.0. Resending the message:

I've Thunderbird 78.4.0 on a Macbook Pro running Catalina 10.15.7. While my Mac and the internet connection is v fast, Thunderbird is extremely slow in all actions - reading emails (even if there's only 1 new email), replying, even clicking on a folder brings up the blue wheel. I've only added 3 of my email accounts as of now, 2 of which are very new with v few emails. I've NO add-ons currently. I'm wondering if I should just uninstall it.
