Maybe not the correct place but...

Although the solution is not obvious, it can be done without installing any extensions.

You can setup a whitelist for your daughter, so that she can only view the pages that you specify are OK. Here is a guide that will show you how:

You can make a new profile for your daughter, to keep these settings from applying to you, or you can just enable the proxy setting when you hand it over to her, and disable it when you start again.

This is something that fits more as an extension than an actual feature. You will be very interested in the work Glaxstar is doing. They are working on an extension called OwnArea which will be very useful as a dynamic filtering tool. Check out their site, their beta version is coming out soon!

I won't be the one to write this extension. It provides the illusion of safety (that so many crave, especially parents who don't want to be burdened with raising their children).

Bottom line: if you children are on the net, and want to research AIDS on AIDS day, they shouldn't be blocked because it isn't a kids game site. And if they want to surf Wikipedia absorbing knowledge on a wide range of topics, they shouldn't be blocked just because it has mixed content. The WORLD has mixed content. While your children are using the 'net, if you feel that they are not able to handle things they are likely to come across, then BE there. While there, with a list of excellent bookmarks (wikipedia, discovery, etc) your kid can use the net, communicate with friends, be satisfied with what you've allowed, and still be as safe as anyone can be.

The above site advocates that the net should not be censored from children, especially teens. If you can't see why, then imagine your government limiting what you can see on the net because it is "wrong" or "bad". Not the same, but a good comparison. It ends up hurting more than it helps.

Having said all that, this extension would probably help spread Firefox, and give it some great posative plublicity.

It wouldn't have to be foolproof, just a little workable white list, and a XOR encrypted password or some such. Nothing special... but it would work for most younger kids. It could have options like:

 Allow/Dissallow: Javascript, Java, Flash, embedded video, embedded audio
 A *simple* white list manager
 A URL to direct to when blocked (could be a local file blocked screen, or Discovery for Kids, the person settting it up decides).

 One of the most important things would be the wizard. It would ask for a good password, walk the parent through what to disable or enable (good defaults, with explanations of each)  and give a recommended age range that this extension is designed for, and explain that any serious attempt by a more computer savvy person to defeat the blocks will likely succeed (and recomend monitoring in conjunction with this extension, like placing the computer in the living room/family room).

And several other very easy, small, and simple features I am thinking, but will not bother to list at this time.

 Then again, a five minute education from a good tech could enlighten and educate the parent enough to provide for a better setup for both the parent and the child - with no blocking software.
