Adblockers are fairly popular plugins these days... little do most people know, these ad-ons typically only block the display of advertisements; this still allows analytical data to be gathered by data-mining organizations, leaving you vulnerable to tracking.
Mac OS Step 1) Download and expand this modfiied hosts file to your desktop (not a trojan / virus, guaranteed... the file is a simple .TXT which you can examine at your leisure).
Mac OS Step 2)Launch Terminal.app, located here: Macintosh HD > Applications > Utilities > Terminal.app
Mac OS Step 3) Back Up your original hosts file with this command:
cp /etc/hosts ~/desktop/hosts_old.txt
Mac OS Step 4) Assuming you followed step 1, enter this command:
sudo cp ~/desktop/hosts.txt /etc/hosts
When requested, enter your user account password (the one you log in with)
Enjoy an entirely new internet experience! Should you run in to any problems, use this command to restore the original host file (saved on to desktop in step 3 above):
sudo cp ~/desktop/hosts_old.txt /etc/hosts
Also, just FYI: this is hulu-compliant, but some media websites won't load without first playing an advertisement. Revert using the restore procedure above if you can't load something correctly.
