Problem Description

If you are using Firefox v53 through v56 with Forcepoint One Endpoint solutions on Windows machines, use this deployment guidance to install the extension silently. These steps are not needed if you are using Firefox Quantum v57 or higher.

Resolution

When deploying the Forcepoint One Endpoint software to Windows machines with Firefox v53-v56 installed, users may see a prompt the next time they launch Firefox stating that the Forcepoint One Endpoint extension was added to Firefox. If an organization prefers to install the extension silently, follow the below deployment guidance:

Forcepoint Web Security Direct Connect Endpoint:

Edit the DCUserConfig.xml configuration file to specify the following configuration parameters in “DCSetting”:

<FirefoxSetting FirefoxConfigCFGFileName="mozilla.cfg" FirefoxConfigJSFileName="channel-prefs.js" />

Forcepoint Web Security Proxy Connect Endpoint:

Edit the HWSConfig.xml configuration file to specify the following configuration parameters in “ProxySetting”:

<FirefoxSetting FirefoxConfigCFGFileName="mozilla.cfg" FirefoxConfigJSFileName="channel-prefs.js" />

Forcepoint DLP Endpoint:

Edit the following configuration files to enable silent installation of the Firefox extension:

  1. Open the Firefox installation folder. For example: C:\Program Files (x86)\Mozilla Firefox\defaults\pref.

  2. Add the following text to the channel-prefs.js file:

    pref("general.config.obscure_value", 0);

    pref("general.config.filename", "firefox.cfg");

  3. Create a new file named firefox.cfg and put it into the Firefox folder. For example, C:\Program Files (x86)\Mozilla Firefox.

  4. Add the following text to firefox.cfg:

    // empty comment up top - must be here

    defaultPref("extensions.autoDisableScopes", 0);

    defaultPref("extensions.enabledScopes", 15);

Restart Firefox.
