I have Mac Os 10.15.6.
I am trying to backup the profile folder.
Not able to find it.
tried the go to command ,no success as well.
Thunderbird version 68.10.0 64bit
Help/Troubleshooting, click Show in Finder to open the profile folder. Close TB before cop profiles.ini. Restoring the Thunderbird folder will restore the complete set of user data.
