Let Torbutton Spoof the specific OS and FF build.
When testing the latest Torbutton development version on this website : http://www.cyscape.com/showbrow.aspx?bhjs=0, the original platform "OS" used was revealed, thus reducing anonymity. It would be nice if Torbutton could spoof the clients OS randomly, making it harder for exit notes or websites to take the first step in determining your identity. This could also be standardized as a single "spoofed OS". (as was done with v1.1.14 24 Feb 2008 "spoof an English browser").
The specific Firefox build number was also revealed in the same manner. This in combination with the identification of ones OS, makes it more likely that a pattern could be seen. Especially when someone uses a less common OS. To counter this problem, Torbutton could randomly spoof all the FF version numbers between the first and last build. For instance for FF2, anything between 2.xx and 2.xx.14 and for FF3 in the same way. Or again using one specific build number for all.
