Howerver, TPB has developed a Firefox-based browser it calls PirateBrowser that uses the Tor network and allows users to bypass ISP filtering and access blocked Web sites. As of May 2014, it has been downloaded by more than 5 million users. In addition TPB is developing a P2P BitTorrent browser application that will let its users distribute and store the site and others on their own computers without having to access a central host. Once it releases thes application, TPB will no longer have a central location for attack, and piracy enforcement efforts may become even more difficult. In July 2014, it launched a mobile version that it calls The Mobile Bay. It also plans to develop separate television, Music, and movie sites, all in an effort to make it even more resilient than it has been.
