Don't know if this still works but give it a try:

For Canadian viewers, if you are using firefox, install the following addon:
http://addons.mozilla.org/en-US/firefox/addon/967 then:
1) In Firefox, Go to tools->modify headers
2) From the drop down box on the left select add
3) Then enter: "X-Forwarded-For" in the first input box without the quotation marks
4) Enter: "12.13.14.15" in the second input box without the quotation marks
5) Leave the last input box empty, and save the filter, and enable it

6) Click the 'Configuration' tab on the right then proceed to check the 'always on' button.
Close the Modify Headers box and it should work.
