In response to redrose and after fiddling with my own browser after trying out https://panopticlick.eff.org, I feel like we should take this further. Regardless of whatever Mozilla wants to do, should the rest of us free software and privacy users (whether Icecat or Tor or else similar), should we come together for a declaration/specification of a common UA? Tor traditionally uses a Mozilla on a Windows type system, but should we do this and identify as Windows also as free software users? And should we even represent Mozilla at all? Or should we have some kind of rotating UA browser plugin? How do you handle your own UA settings?
Should we band together in solidarity for a common UA?
