In Internet Explorer there's Content Advisor, but it's deeply flaws and can be bypassed a number of ways. (Complete disablement takes 10 seconds.) In Firefox, an attempt at such was not made, as there are so many ways of circumventing it, particularly with the way Firefox is designed. It may come in the future, but not now. Also, to my knowledge there is no extension that can do such. However, there are options:
* Modify the HOSTS file, which will block access to the site no matter what browser is used. It's not password-protected, but if he doesn't know about it he may give up.
* Some firewalls have the option to block websites, and are password-protected. Which do you use?
* Download an extension such as Adblock. It's designed to block in-site ads, but can also block websites. It's not password-protected and will announce its presence, but it may act as a deterrent if he's not good with computers, and if nothing else will block ads for you, once properly configured.
* If you use a router there may be an option to block websites through there.
* Use child-protection software...click here for recommendations.
* And, of course, the best option is sit him down and talk to him...correct the issue instead of pushing it aside.
Hope this helps,

P.S. For more information on any of the above, just give a shout back with your system specs and internet setup. (Details, details, details.)
that is not pornographic? I've searched the web for this, but I haven't found any results. I'm looking for a password-protected way to make one website inaccessible.
It sounds very juvenile, but my roommate keeps downloading WordBiz--an online scrabble client--and he claims he's ''addicted'' to it. I've trashed it numerous times, but he keeps downloading it again. So, I wonder if it's possible to block the site. Is this kind of thing possible? Thanks in advance.
