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.
