After the recent Firefox incident I realized how I lied to myself by believing that I'm secure just by using Linux. My setup is Ubuntu 14.04 LTS (job requirement) with XFCE. So here's my question: What is the best Linux sandbox available right now? Even better if it's something simple to use and battle tested. Main things I would like to sandbox is Firefox, Thunderbird, Wine, Torrent stuff and maybe Chrome (is it necessary? my chrome://sandbox shows YES to everything except "SUID Sandbox")
