Firefox embeds too much information in the browser's User-Agent header field (even the build date, which I find unnecessary).
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:18.104.22.168) Gecko/20091109 Firefox/3.5
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:22.214.171.124) Gecko/20100722 Firefox/3.6.8
As a result, User-Agent one uses tends to be unique on a not-so-popular websites, which I would like to avoid to retain certain anonymity on the web.
So, what would be the most common Firefox User-Agent?
