Keeping sensitive data safe from unauthorized access, leaks or misuse is crucial for any organization. Data Loss Prevention (DLP) helps by controlling how data is handled, shared and accessed. Firefox supports DLP by integrating with third-party software to detect accidental or inappropriate sharing of company data. When enabled, operations such as file uploads and pasting of data can be checked by DLP software.

Enterprises have two ways to use DLP in Firefox:

• Built-in DLP (Firefox Enterprise): rules are managed in the Admin Console, and enforced in the browser, no third-party agent is required
• Your own DLP agent: connect an existing third-party DLP product through the ContentAnalysis policy

Built-in DLP

Firefox Enterprise includes a built-in DLP agent. Admins can create DLP rules in the Firefox Enterprise Admin Console without installing or licensing a separate DLP product. A rule describes a browser action, and the domains it applies to, and what should happen.

When a rule triggers, a dialog box appears in the browser with details of the conditions that triggered the rule and either a warning or a block based on the policy. For more information on setting up rules, see our admin docs.

DLP icon

When you see the DLP icon in the Firefox tab bar, it means Firefox is set up to work with an Enterprise Policy to share browsing data with third-party DLP software, which can potentially limit activities like uploading or sharing information.

Can I disable DLP?

DLP is typically used on managed computers set up by IT administrators in organizations and can be turned on or off by them. If you see the DLP icon on your personal computer, it might mean that third-party software was installed by mistake or an Enterprise Policy was applied incorrectly. If this applies to you, ask a question on the Firefox support forum to get help from the Mozilla Community.

Check the path of connected DLP software

When DLP is enabled and Firefox is connected to a DLP agent, information about the agent can be found on the Troubleshooting Information page under the heading Content Analysis (DLP). To access the page:

1. At the top right, click the application menu button .
2. From the dropdown, select Help and then More Troubleshooting Information.
3. Scroll down until you see the Content Analysis (DLP) section.

   
   

If the DLP icon is displayed, but there is no Agent Path listed, it indicates that Firefox has been configured to use DLP via an Enterprise Policy, but is not connected to any DLP agent software on the computer.
