I am thrilled to see that the Tor Browser patches have finally reached Tails.
However, I noticed that FoxyProxy was included. According to   
https://www.torproject.org/torbutton/torbutton-faq.html.en#extensionconflicts
We are not supposed to use Foxyproxy. Also, Adblock Plus, Do not   
track, and the "Tell Websites I do not want to be tracked" check mark   
in Firefoxes settings also can cause concern. I have included   
screenshots in this link <

might cause further issues.
