However, some users find that it's much easier to install a browser add-on that can block websites instead. There are a variety of add-ons published on the Firefox Add-ons website that can offer this functionality, like Block Site (or even Website Blocker, which I created ;-) ).
There are pros and cons to both. Add-ons are generally easier to setup and manage, especially if you are only blocking a few things, but they are very each for someone to disable. Policies are a little harder to setup, but they are far more difficult to circumvent, since they are designed to be used in business environments.
Hope this helps.
