After doing some exhaustive research over a period of time, I could not find an acceptable browser package for Firefox featuring safe and restrictive browsing for kids. Necessity being the mother of invention, I pulled together some extensions and a program to meet my needs.
The Goal
Allow young minds to surf the Internet on what I believe is the safest browser available today – Firefox. Allow the young ones a sense of freedom without letting go of the reins. Allow me, parent and guardian, to view any and all online activity without restriction.
With these goals in mind, I am now using a system that is working well. While it could still use some tweaks, I hope other parents will find this as useful.
Grab a copy of Firefox
Get your free copy of Click to visit this external linkFirefox and install it. Why Firefox? The Click to visit this external linkanswers on Firefox and security, productivity and customization are laid out, as well as why use Firefox instead of Internet Exploder.
If you’re already a Firefox user/fan, that means you’re probably familiar with it’s functions and extensibility. That familarity will help as you set up the browser for your household.
Set up profiles
If your kids will be using Firefox on a computer that is shared, you may wish to set up profiles for different members of the family. To do this, first close any running instances of Firefox. Go to Start › Run › type in firefox.exe -ProfileManager. Click OK. Now Click to visit this external linkcreate a new profile (following the instructions provided in the Knowledge Base). Repeat this for each person in the household.
Tip: To ensure each household member uses their assigned profile, untick the box that reads Don’t ask at startup in the Choose User Profile window. From now on, upon starting Firefox the user will be given a choice of which profile they would like to run.
Set the options
Let’s set up some basic options in Firefox.
Go to Tools › Options. The options window offers many settings, some of which you may wish to further tweak after this initial set up. Some settings will depend on changes we will make later in this article. For now, let’s follow these guidelines:
Main options: When Firefox starts › Show my windows and tabs from last time
Main options: Downloads › Always ask me where to save files (allowing each user to save to their specified folder, optional)
Tabs options: Check › Always show the tab bar
Tabs options: Check › When I open a link in a new tab, switch to it immediately
Privacy options: Remember visited pages for the last › 30 days
Install some add-ons
There are numerous Click to visit this external linkadd-ons for Firefox that can assist in creating a stronger and more secure browser for use by minors. Below are my (current and tested) choices along with some detail.
- Click to visit this external linkdisablemenu – View options image
- “This extension allows you to show/hide the main menu. It can be accessed through a toolbarbutton, keyboard shortcut and popup-menu-item. It also supports autohide. the statusbar can optionally be hidden.”
Little hands can’t get to what they can’t see. In fact, they never have to know the toolbar items exist. Tip! Be sure to set your own Hotkey in the options dialogue. Don’t use the hotkey combo in my example image, but one you can remember instead.
- Click to visit this external linkPublic Fox – View options image
- “Block downloads. Prevent browser changes. Locks down Add-ons, Preferences, ‘about:config’, Bookmarks. Blocks unwanted Web Sites. All with a central password.”
This add-on keeps those little hands from altering the browser’s settings even if they’ve gotten lucky and keyed past the disablemenu add-on. Even viewing the History in the sidebar can be password protected (so no one without a password can delete the history).
More options are set to be added in a future release of this add-on and the developer is active and responsive.
- Click to visit this external linkTab Mix Plus – View options image
- “Tab Mix Plus enhances Firefox’s tab browsing capabilities. It includes such features as duplicating tabs, controlling tab focus, tab clicking options, undo closed tabs and windows, plus much more. It also includes a full-featured session manager.”
This add-on is fundamental to a smooth and user-friendly browsing experience. The session manager alone is worth the download.
To view the settings I’ve used, click to download my Click to visit this external linkexported settings file. To import these settings, save the file and use the Settings/Import option in the Tab Mix Plus dialogue window.
- Click to visit this external linkToolbar Buttons
- “This extension adds buttons to the Customize Toolbar Window. There are now 95 buttons for Firefox, 58 for Thunderbird, and 26 for Sunbird. If you don’t want so many button in one extension you can choose individually from a list here:- Click to visit this external linkcodefisher.org link.”
This add-on whittles the toolbar down to only the necessary items and can keep kids from getting too curious about all of Firefox’s functions.

My buttons of choice are Exit, Back, Forward, Reload, Stop, Home, Cut, Copy, Paste, New Tab and Print. I’ve found that, for kids, the fewer bells and whistles to play with (i.e. alter and break), the better.
Install K9 Web Protection

Click to visit this external linkK9 Web Protection by Blue Coat is an invaluable piece of free software. “K9 Web Protection is our free Internet filtering and control solution for the home. K9 puts YOU in control of the Internet so you can protect your kids.” The benefits of using software like this are numerous. Here is a general list of features provided with K9:
- Block 60 Content Categories (MySpace, adult humor, etc.)
- Time Restrictions (10pm – 5:30am is my set blocked time)
- Web Site Exceptions (I allow some Last.fm usage)
- Blocking Effects (Extended blocking, sounds, etc.)
- URL Keywords (Block all sites with sex in the URL)
- Web Search Options (Enforce safe searching)
- View Reports of Internet Activity (Log viewing)
As an alternative, an additional Firefox add-on named Click to visit this external linkProCon Latte can help to block unwanted Internet content from your computer. “ProCon is a content filter for the Firefox browser. It can filter any kind of material (pornography, gambling, hacking, cracking, etc…), it can also block all traffic, making sure that only desired websites (set in the Whitelist) can be accessed, and includes a profanity filter, all *like* a parental control filter.” (I have not tried this add-on. While it certainly would be a great addition, K9 provides some options not available with add-ons – time restrictions, logging, etc.)
With the above arsenal of products, add-ons and settings, your children’s browsing activities will be more protected than ever. Please note though, nothing is 100% failsafe or foolproof, but doing something is always better than doing nothing.
For further security, Click to visit this external linkdisable other browsers (e.g., IE!), move home computers to more public spaces within the home, and let the kids know they are being monitored. And lastly, be sure to set up some basic house rules and have each kid pledge to abide by them.

You’ve done a really great job of assembling a good guide to introduce Firefox and how to get the most out of it.
One thing that I’d like to add is that there is a (free) program called Glubble that is basically a super safe and kid friendly version of Firefox designed for children up to 12 years old. It’s definitely worth checking out.
And just so that you are aware, I run a web site called Access Firefox that offers all free Firefox tools and resources for persons with various visual impairments.

Great article… a must read for parents. If you get a chance, take a look at Kiddix. Kiddix is a whole operating system for kids that I think is built on Linux. They have a neat ‘kiddie’ version of Firefox that has parental controls, and a bunch of useful tools like encyclopedia search. My kids really enjoy using it.
