Major features in Tails 1.4 include the anonymous Tor Browser 4.5 web browser software based on Mozilla Firefox ESR, a shortcut for the Tails OpenPGP Applet, which has been added to the Gedit text editor, and Paperkey, a tool that allows users to print a backup of their OpenPGP secret keys on paper. Disconnect is now the new default search engine in Tails 1.4, providing Tor users with Google search results without bans or captchas.
