Hi, i am on an 2008 macbook pro, with 10.11.6 installed (cannot update further) I am using Thunderbird beta until 80 beta 5, since i cannot update to the further beta released, i would like to downgrade to the current official release (78). How I can do this with my current profile?

Thank you and looking forward to your reply.

Uninstall Thunderbird. Download and install current version from here: https://www.thunderbird.net/en-US/thunderbird/all/

On the last step of the installation do NOT select to start TB. You will need to run a command to allow you to downgrade and you will have to select the profile with Profile Manager and include --allow-downgrade in the command line, e.g. for OS X:

/Applications/Thunderbird.app/Contents/MacOS/thunderbird -profilemanager --allow-downgrade


Profile Manager starts so you can select the desired profile name, then click on 'Start Thunderbird'.
