Transferring from ThunderBird 68 to ThunderBird 78
I've been running ThunderBird 68 and was curious when I noticed that there was a ThunderBird 78. I've downloaded and installed it on MacOS X Catalina side by side with v68. I had hoped that v78 would locate and recognise my settings from v68 but it hasn't.
Is there a way to simply point v78 to the settings of v68?
