Source code
A maior parte dos programas inclusos no Tails são tirados diretamente dos pacotes do Debian e não são nem modificados nem recompilados por nós.
O código fonte dos programas que são específicos do Tails está disponível em nossos repositórios Git.
The source code of the Debian packages included in Tails is available in the APT snapshot that we created for that version of Tails.
The red theme used by Tails' Unsafe Browser was downloaded from Mozilla add-ons website (https://addons.mozilla.org/en-US/firefox/addon/simplyred/):
