Block Siteby Ray

This extension is meant to block website access. There is a master password that can be set for temporarily allow accessing one or multiple blocked websites. A user can add or remove blocked hostnames form the options page if he or she has access to the master password. It is also possible to use this extension to redirect a hostname to a new destination. For instance, it is possible to redirect google.com's search results to bing.comsince this extension keeps the URL params when performing redirection.
