Mozilla: New #Firefox #Extensions must disclose #Data #Collection #Practices.
The devs will be required to disclose any new extension's data practices in the manifest.json file using a dedicated browser_specific_settings.gecko.data_collection_permissions key beginning today. Mozilla will also require all extension developers to adopt this framework in 2026.
