7.5 Disabled Recommended Extensions

Information

This setting configures if Firefox can send recommendations on extensions based on user data as they navigate the web.

Rationale:

Enabling recommended extensions could allow data to be transmitted to a third-party, which could lead to sensitive data being exposed.

Impact:

Recommendations on extensions will not be extended to users.

Solution

To establish the recommended configuration, set extensions.htmlaboutaddons.recommendations.enabled to false:

Type about:config in the address bar

Type extensions.htmlaboutaddons.recommendations.enabled in the filter

Ensure the setting is set as prescribed.

OR

Open the mozilla.cfg file in the installation directory with a text editor

Add the following lines to mozilla.cfg:

lockPref('extensions.htmlaboutaddons.recommendations.enabled', false);

Default Value:

True (Enabled).
