DisableThirdPartyModuleBlocking

Do not allow blocking third-party modules (DLLs) from the about:third-party page.

This policy only works on Windows through GPO, not via policies.json.

Values

• Set to true to stop users blocking third-party modules from about:third-party.
• Set to false to leave third-party module blocking available. This is the same as not setting the policy.

Examples
