Hello,

I need to secure the proxy from users, users can't modify the information and they should be locked.

I've been looking for the method and i've created 2 files mozilla.cfg and local-settings.js when i go to see the proxy setting they are not grey and it can be modified i don't know what is the reason at all ...

mozilla.cfg content :

//

// Disable updater

lockPref("app.update.enabled", false);

// make absolutely sure it is really off

lockPref("app.update.auto", false);

lockPref("app.update.mode", 0);

lockPref("app.update.service.enabled", false);

lockPref("network.proxy.type", 0);

local-settings.js content :

//

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

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

Path :

Mozilla.cfg = C:\Program Files\Mozilla Firefox

local-settings.js =C:\Program Files\Mozilla Firefox\defaults\pref

I think that your code should work (works for me).

Did you check the Browser Console for possible error messages ?

The autoconfig.cfg file is placed at the top level of the Firefox directory.

  • autoconfig.cfg and autoconfig.js need to start with a comment line (//)
  • autoconfig.js needs to use Unix line endings (LF instead of CR/LF)

To access proxy settings in Mozilla Firefox, click on Firefox's menu and go to Options. Click the “Advanced” icon at the left side of the Preferences window, click the “Network” tab at the top of the window, and then click the “Settings” button under Connection. You can select four different proxy options here

Hi,

Please see this.

The settings you may want to lock are network.proxy.http and network.proxy.http_port or network.proxy.autoconfig_url
