About the DNS, is there some reason why you haven't simply routed DNS requests through the tor proxy as described here: http://superuser.com/questions/10359...oxy-in-firefox I just tried it and it seems to work.

Despite the comments about vulnerabilities in tor-browser I would still like a dedicated tor browser on my Jolla. Long story short, for real security I use whonix and I certainly would't trust anything important to a hand-held device that holds my data unencrypted.
