A little condescending and obnoxious for my taste but mostly everything here is well-known and while the TOR-Browser devs could implement everything this guy wants it, and it will end in a moral dilemma of what could be considerable "malicious". IMHO the Tor Browser is not suitable for the truly paranoid but usually this wont matter because the truly paranoid is not using the TOR network as-is (with the integrated browser) and those who aren't truly paranoid can live with those risk.
