For fingerprinting try Firegloves (only for firefox). Copy-paste user-agents from any site having a list of these to addons preferences.

Also to provide more privacy with cookies we could use cookie-managers like CookieMonster or CS Lite Mod (both for Firefox). I prefer the second since it stores my settings instead  of the first one, which it doesn't.

But the real power, for firefox, is in about:config. Test these settings and tell me your experience/results. (Sorry for the long legnth)

geo.enabled = false

geo.wifi.uri = [leave blank]

network.http.accept.default = text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

intl.charsetmenu.browser.cache = ISO-8859-9, windows-1252, windows-1251, ISO-8859-1, UTF-8 = false

extensions.blocklist.enabled = false

(the network.http.sendRefererHeader = 0 and network.http.sendSecureXSiteReferrer = false made my Collusion addon graph clear. This means the no referer was sent to any website and worked). Waiting for your thoughts.

Deleted your duplicate post :) In regards to Firegloves--thanks for the recommendation! According to the page on Firefox, though---they're going to stop supporting it so we're hesitant to recommend it on 

Hopefully, someone can fill this gap with a new addon because, as far as browser fingerprinting goes, there aren't too many addons out there with respectable track records and reliability.
