Quickly block all content from Facebook in one swoop

Want to block Facebook entirely for yourself or someone you care about? It’s easy.
Instructions for a Mac OS X:

Step 1:

Open up Terminal (It’s in Applications/Utilities) and enter this text and hit enter, followed by your password:

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts

This is your hosts file, which is the first place your computer checks for DNS lookups.

Step 2:

Add this line: facebook.com

Once your hosts file looks like this, save it: hosts

Open Terminal again and insert this: dscacheutil -flushcache. Then restart your browsers and your machine to be certain your DNS cache is flushed down the drain.

On a PC:

1) Right click on Notepad and pick Run as administrator. Click on File then Open then browse to windowssystem32driversetc In the drop down list change Text files (*.txt) to All files (*.*)

2) Open the hosts file and add facebook.com

Reduce those life minutes:
