IMPORTANT: These files are in active development along with the policies in Thunderbird. To get the policy information that corresponds to a specific release, go to https://github.com/thunderbird/policy-templates.
Starting with Thunderbird 68, Thunderbird supports configuration files on macOS.
An example plist file with all options is available here:
If you want to set specific options from the command line, we also provide flattened shortcuts to any item that is nested in the plist file.
For example, this policy:
{
"policies": {
"Proxy": {
"HTTPProxy": "proxy.example.com:80/"
}
}
}
which would be set in the plist file like this:
<key>Proxy</key>
<dict>
<key>HTTPProxy</key>
<string>proxy.example.com:80</string>
</dict>
Correctly writing the nested value with the defaults command can be hard, so you can flatten the keys by separating them with __, like this:
sudo defaults write /Library/Preferences/org.mozilla.thunderbird Proxy__HTTPProxy -string "proxy.example.com:80"
Before any command line policies will work, you need to enable policies like this:
sudo defaults write /Library/Preferences/org.mozilla.thunderbird EnterprisePoliciesEnabled -bool TRUE
