This question comes up a lot. You can do some rudimentary filtering with GP for Internet Explorer by modifying the Content Ratings in IE Maintenance Policy (under User Configuration > Windows Settings) however, this is a poor approach to say the least. Unfortunately, there is nothing you can do natively in GP for Mozilla browsers (wouldn't make sense for Microsoft to promote the use of a competing product). There is, however, a FirefoxADM project on SourceForge.net that allows you to control quite a bit of Firefox configuration via GP, although I don't know if you can do any kind of website blocking. I haven't used it in quite a while. Your best bet is to use a proxy server/content filter in your network and block sites at that level. There are lots of free ones out there, but my favorites are Squid/DansGuardian. They come pre-installed in SmoothWall Express, which is a free Linux based firewall appliance capable of supporting small to medium sized businesses. All you need is a semi-decent piece of equipment to install it on and you'll be blocking websites in no time.
