I have read probably 100 of your help topics and none of them seem to address my topic in plain english. I have used Thunderbird for years on a windows computer (currently windows 10, Tbird Ver 78.6.0) and I am trying to move my profile from my windows computer to a new Mac running Big Sur Ver 11.1. Thunderbird (for some unknown reason) actually created 4 different profiles on my windows machine (two under: users/alan/AppData/Local, and the same two profiles under users/alan/AppData/roaming) but I have figured out which profile that Thunderbird is using based upon the help/troubleshooting/profile folder/open folder (which happens to be one of the ones located under: users/alan/AppData/roaming) and it is 13.9GB. I copied this folder (and all included files) to a jump drive so that I could move it to my new Mac.
I am new to Apple and know nothing about their operating system. I downloaded Thunderbird from the Mozilla website and installed it according to their directions. I finally found the default profile on my Mac that was created when I installed Thunderbird and I deleted it. I copied my existing windows profile to the same location. Now when I start Thunderbird I am greeted with a message that states: "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."
Obviously I have done something wrong. Please direct me how to correct my problem -- it seems like this should be pretty simple, but I am lost.
Thank you very much!!
