I'm using a Macbook Pro as a productivity/work machine and have Facebook and reddit blocked with /etc/hosts:

# Host Database
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##       localhost broadcasthost
::1             localhost 
fe80::1%lo0     localhost         facebook.com
::0             facebook.com         reddit.com
::0             reddit.com

This has worked for a while in all browsers, but recently stopped working in Firefox and Safari, and I can't figure out why. I was previously using, but when that stopped working I tried instead, no dice.

I did install Avast just recently so I thought that could have been the problem, what with its web security features, but I uninstalled the browser add-on in Safari and Firefox and I was still able to access Facebook and reddit just fine.

And I just tried uninstalling the add-ons again, and restarted the computer. Now, Google Chrome can access Facebook, but not reddit. Firefox can't access either, and Safari can access both...

I'm using OS X 10.7.5.

I solved my problem. It seems I need to block both the domain website.com and the address www.website.com. I didn't know that was necessary. I edited them in there and now the blocking is consistently working everywhere.


The following site clearly explains how to block a site step by step using hosts on etc by means of terminal: wikiHow-Block a Website on Mac

  • Answers on Ask Different need to be more than just a link. It's okay to include a link, but please summarize or excerpt it in the answer. The idea is to make the answer stand alone.
