Solomon: tsocks won't work with the Microb browser in Diablo, since the browser's engine, the "browserd" daemon, starts up when the tablet starts up and so it can't really be run through tsocks. Other applications should still run fine through tsocks. I ran VNC viewer through tsocks the other week and it worked.

My about:config method probably still works in Diablo, although I haven't tried it recently, since I haven't been browsing on any particularly untrusted Wi-Fi networks lately.
