This article explains how to prevent children from using Firefox, block websites or filter website content in Firefox that may be offensive or inappropriate for children.
Parental controls and web filtering software
Firefox checks the parental controls on your computer and sets itself to Prefer:Safe mode. This automatically turns on the safety feature on each website your child visits, as long as you have the parental controls active on your computer.
This feature can be turned off only through your password-protected parental settings on your operating system, so your child will not be able to deactivate this feature through the browser.
To turn on parental controls on your computer, please see the support documentation for your operating system or see the following:
- Getting started with Microsoft Family Safety at microsoft.com.
- Set up family features on Windows 10 at microsoft.com.
- Set up Family Safety at microsoft.com.
In addition to parental controls built into your operating system, third-party software is also available. For a list of web filtering software, see Comparison of content-control software and providers at wikipedia.org.
Web filtering extensions for Firefox
This addons.mozilla.org search for parental control lists several extensions that can provide content blocking.
