Learn about the Microsoft Purview extension for Firefox

Endpoint data loss prevention (endpoint DLP) extends the activity monitoring and protection capabilities of Microsoft Purview data loss prevention (DLP) to sensitive items that are on Windows 10/11 devices. Once you onboard devices to the Microsoft Purview solutions, the information about what users are doing with sensitive items is made visible in activity explorer. Then you can enforce protective actions on those items via DLP policies.

After you install the Firefox extension on a Windows 10/11 device, your organization can monitor when a user attempts to access or upload a sensitive item to a cloud service using Mozilla Firefox, and enforce protective actions via DLP.
