Cannot help in some countries, not your fault: Rated 4 out of 5 stars

Government of China uses DNS poisoning [domain name server alterations] to prevent citizens from accessing social netwoking sites ever, including among others Facebook i think and YouTube for certain. This Add-on therefore would not help you access those sites blocked at the server level by your government if you live in China, so that was not a good reason to give it a bad rating. You likely did not know this.

This review is for a previous version of the add-on (0.3.2).
