Check out my extension RandomUA, which randomizes your User-Agent header for each request in a way that preserves compatibility but really mucks up tracking.

@tindall often with these randomizers, the biggest fear I have is the sites where i purchase stuff from or pay my bills in are not able to track if am the same entity being sent to the payment gateway. am not sure if ua is part of their consideration but it's been a really bad experience.
