How can I use Tor on Firefox OS? Is there anything like Orbot or a browser bundle for Firefox OS based phones?

No, currently there is no way to use Tor on Firefox OS based phones, because there is no way to run the Tor program on Firefox OS. But it might be possible in the future, though no projects are working on it right now

We've [Guardian Project] talked to Mozilla multiple times about this possibility. They even invited us to a special event in Mountain View around a "secure Firefox phone".

The main issue is that they don't want to allow native binaries to run on the device as part of apps themselves. We can easily write an HTML/JS controller GUI, aka OrbotHTML, but we can't bundle in a native Tor arm binary into that app, apparently.

However, there is now a Javascript implementation of Tor that could potentially be ported to Firefox OS, but there are currently no plans in progress to do so.


If I may: The real problem seems to be that JavaScript is essential to Firefox OS and JavaScript is a big no no for Tor. From https://lists.torproject.org/pipermail/tor-talk/2013-July/028740.html we see

They said we must cross-compile any native code into Javascript. I am not sure if that was meant to be a joke or not.

and at http://archives.seul.org/or/talk/Jul-2013/msg00121.html you can see this explicitly stated as:

That is the rub, obviously. A FirefoxOS phone is built around the concept of JavaScript as the primary application programming language. If JavaScript is off, then the phone might as well be bricked.
