Upgrade to 78.4.1 [win10]
My Thunderbird just upgraded to 78.4.1 and is now unusable. It is slow to load and move around, email messages don't load, I have to run my cursor over the menus to get them to appear. I have Windows 10 and exceed all of the recommended memory and system requirements. How do I either fix this or revert back to an earlier version that is usable?
