Pirate Browser's makers are careful to warn that the browser will not allow you to surf the net anonymously. Instead, the browser is supposed to help you circumvent "the censoring / blocking of websites your government doesn't want you to know about." In many cases, this means the Pirate Bay's site itself.
We put this claim to the test, getting our friends in Singapore to attempt to access government-blocked sites with Pirate Browser. They were unable to access restricted sites such as YouPorn and Redtube, seeing the same government warnings on those sites as they did on other browsers.
However, we had greater success in the U.S. After our administrator temporarily blocked access to torrent site Fenopy.se, we were unable to access the page on Chrome, but could view it on Pirate Browser. However, Pirate Browser did not get around a block on Games.com.
