If you want to watch Hulu or one of the US TV network's webcontent (which is usually solely for US residents) and have never been able to because it requires you to be watching in the US... this guide is for you.
How to bypass the country check at South Park Studios and in other places.

1. Get Firefox.
2. Download & Install "Modify-Headers"
3. Go to Tools -> Modify Headers
4. Click Configuration and check Always On: Enable ... and Open Modify Headers ....
5. At the top select "Add" from the drop down list. Type in X-Forwarded-For in the field to the left of the drop down list and 12.13.14.15 in the other one. Nvm the third field
6. Press "Add" and select your new lines and press Enable/disable if it isn't already enabled.
7. ????
8. Profit and watch South Park.

If someone can confirm that this works, it would be great.

Update: ok this doesn't seem to work for Hulu but it did work for comedy central. For Hulu, seems there are these VPN solutions.
