I'd like to prevent Firefox from reading canvas, for example. As far as I understand, this is functionality of Tor Button extension which is part of Tor Browser Bundle, but it implies using Tor. What if I want to achieve the same protection in the regular Firefox for non-Tor browsing, what should I use?
Update: question was marked as duplicate of How to dissconnect Tor browser from the Tor network but I don't think so, because that question is about using TBB without Tor, and the consensus was that it's a very bad idea. And my question is about the opposite — getting TBB-level browser hardening in a regular Firefox (or some fork) for using it with regular browsing (not over Tor).
firefoxbinary shipped with Tor Browser is exactly that, but I don't know of anyone packaging it specifically.
