Using a whitelist, a blacklist, or the default setting, you can block websites based on a list of known sites that you want to visit. This can be useful if you want to surf the web anonymously, while also limiting what you see.

With the whitelist feature, you have the option to set which sites can be visited.

With the blacklist feature, you can specify which sites can be visited, except for the ones you specify in the whitelist.

By default, your browser will open new pages in a separate window, which you can then close. This feature can be disabled in the options of this extension.

You can also change the order of sites on the blacklist, so they can be visited in a different order, or one at a time.

This extension also has options to enable/disable blocking for all websites (by default, it is enabled), to block or allow JavaScript (this is disabled by default), to block images, and to block cookies and ads.
