I'm not sure what your point is. Backing this out still wasn't necessary
and it still fixes an issue for fennec.

I get "Thank you for trying a nightly build and helping improve future
versions of Firefox" here
(http://www.mozilla.org/projects/firefox/prerelease.html). Might be
because they sniff the Firefox token.

Title:
  Firefox user-agent string is too unique

Status in The Mozilla Firefox Browser:
  Fix Released
Status in “firefox” package in Ubuntu:
  Triaged

Bug description:
  As shown on http://panopticlick.eff.org

  The useragent string "Mozilla/5.0 (X11; Ubuntu; Linux x86_64;
  rv:10.0.2) Gecko/20100101 Firefox/10.0.2" is too unique and in
  combination with a fairly unique plugin list this allows browser
  fingerprint tracking, which is bad for privacy.

  I would suggest this change:
  Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:10.0.2) Gecko/20100101 
Firefox/10.0.2
  Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0

  This removes makes the version number less unique. Also the Gecko
  version could be made a bit more generic.
