How to Disallow a Site from Opening

I recommend this be used by Apple users who are high-end. If you are not a high-end Apple user., then use your browser settings. Use at your own risk.

Excellent for Parental Control:

This is an important tool to use for parental controls and for yourself when you want to avoid visiting particular sites that you never want to visit.

Disallowing a Site from Opening:

This is Performed in Terminal:

Use the Host File Database in Terminal to perform this. Because all three of these sites use IP Version 6, the address must start with: fe80::1%lo0 (for note:, if IP Version 4, just include the site name, without fe80::1%lo0 ).

So, for instance, the following are what to use in steps 3 and 4 shown below:

Facebook:

fe80::1%lo0 www.facebook.com
fe80::1%lo0 facebook.com

Twitter:

fe80::1%lo0 www.twitter.com
fe80::1%lo0 twitter.com

Parler:

fe80::1%lo0 www.parler.com
fe80::1%lo0 parler.com
