A system for selectively allowing and restricting access to websites requested by a user includes a computer having a central processing unit, a display, a keyboard and a web browser installed on the central processing unit. The web browser has a list of allowable top level domains (TLDs), and the central processing unit includes a database having a list of allowable uniform resource locators (URLs). The web browser compares the TLD and URL associated with a requested website to respectively determine if they are the same as a TLD or URL in the lists of allowable TLDs and URLs. If either the TLD or URL associated with the requested website is the same as a TLD or URL on the lists, the user is allowed to access the requested website on the computer. If neither the TLD nor the URL associated with the requested website is the same as a TLD or URL on the lists of allowable TLDs and URLs, the user is denied access to the requested website on the computer.
