Thunderbird and Upgrade to Mac OS 11.0.1 - Big Sur

more options

I just installed the Big Sur Upgrade. When I went to open Thunderbird I got the following message: "Profile Missing: Your Thunderbird Profile cannot be loaded. It may be missing or inaccessible." With this message, I am unable to open Thunderbird at all.

How do I find and restore my Thunderbird Profile?

The problem was solved when I restarted my computer. It asked for the iCloud passphrase. Once in iCloud, the missing profiles repopulated Thunderbird and it works well now.
