Configuring InFilter

  1. Manage your InFilter configuration by changing your settings

Locking Down Your System

  1. Remove all other browsers besides Firefox (instructions will vary by operating systems)
  2. Configure Firefox
    • Make the following changes to settings:
      • Remove search engines you do not wish to allow (to avoid them being used)
      • Set homepage/new tabs to blank page (to avoid Firefox content from popping up)
    • Install a Firefox policy that restricts InFilter from being tampered with
      • Download our recommended Firefox policy file, which sets all of our recommended Firefox policies
      • Copy the policies.json file into the Firefox installation directory
        • On Linux, the file goes into firefox/distribution, where firefox is the installation directory for firefox, which varies by distribution. On Linux, this is commonly /usr/lib/firefox/distribution
        • On Mac, the file goes into
        • On Windows, create a directory called distribution where the EXE is located and place the file there

Adding Further Protection

Though InFilter keeps your family, friends or students within the Internet you create, you may have other devices around that do not have InFilter installed. In order to protect yourself and others on these devices, we have a few suggestions:

  1. Setup a DNS-based filter like CleanBrowsing or OpenDNS on your router. This will protect all users on your network. Even though you may set your children up on InFilter, a great choice, it is possible they could gain access to your devices and you won’t want them having unrestricted access. Furthermore, using a DNS-based filter protects you from content like malware, advertising sites and many other types of undesirable content.
  2. Use Steven Black’s Hosts file to block ads, malware and other junk

Starting On A New Laptop

You might want to setup a laptop for your family, friends or students to use to access the Internet. If you’re starting from scratch, we recommend the following:

Install Ubuntu

Ubuntu is a free, open-source operating system that has many great applications available for students. It is also very secure, since it is based on Linux, which runs most of the world's most important computers.
  1. Prepare a USB stick of at least 1GB in size
  2. Download UNetbootin, which will allow you to download & make an bootable USB
  3. Install Ubuntu onto your computer
  4. Boot your newly installed Ubuntu operating system!
  5. Remove the following packages:
    • All “Ubuntu Lens” and “Scope” related packages, that may allow Internet access, such as searching for images or videos
    • Turn off dash plugins
    • All web browsers other than Firefox (webbrowser-app, webapp-container are two to check for)
    • Any package related to Amazon
  6. Turn off Guest Session
  7. Configure InFilter in Firefox
  8. (Optional) Install educational packages
    • Install edubutu packages based on the age level of the user
  9. (Optional) Secure root account & sudo, which could be used by an advanced user to disable Firefox policies or remove Infilter
  10. Have fun!
