Require password for blacklisted sites
Disable access to the websites you specify. When a blacklisted website is visited, it asks user for password. If user doesn't know password, he is not allowed to access the website. Ideal to protect kids from youtube crap.
This extension is only for my personal purposes, because it is no longer possible to add own chrome extensions to chrome without going through the chrome store. It is ridiculous that Google now charges money even for myself using my own extension on my own browser ... anyway, no support will be provided for this item. help yourself :)
