If I do a complete reinstallation of the Mac Mojave OS, how will this affect my Thunderbird? Will I lose my preferences? Will I lose the folders I've created for sorting incoming mail?

Chosen solution

As with any OS reinstallation, all files are removed.

Suggest you perform a backup of your thunderbird profile first. Mac OS X Profile folders are located here: ~/Library/Thunderbird/Profiles/<Profile name>/ Exit Thunderbird first Access the Library and copy the 'Thunderbird' folder to an external drive. The tilde character (~) refers to the current user's Home folder, so ~/Library is the /Macintosh HD/Users/<username>/Library folder.

After reinstalling the OS and performing all necessary updates. Download and install Thunderbird from this link: https://www.thunderbird.net/en-US/thunderbird/all/ Choose your prefered language and select the download for your OS.

Run Thunderbird the first time and it will create a default profile. Do not bother with creating mail accounts, just Exit Thunderbird.

Access your backup and copy the backed up 'Thunderbird' folder Access the new default profile: ~/Library/Thunderbird Delete that 'Thunderbird' folder. Then paste the copied backup 'Thunderbird' folder into the 'Library' folder.

Start Thunderbird and it should now use your original profile.
