Update (#1) for FF hacks (Was: Re: Easy Firefox hacks to improve anonymity)

[Anothony Georgeo <anogeorgeo@xxxxxxxxx>]

Update #1;

These updates are hacks to the "about:config" menu to
improve anonymity and the anonymity set by increasing
the scope of the Tor HTTP/S Header template. 

A double asteric "**" denotes an important update
hack.

Great page on RFC specs for "Header Field Definitions"
at cotse <http://www.cotse.com/CIE/RFC/2068/155.htm>

-------

To all: Please read and tell me your opinions.
 
-------

The anonymity set that I am attempting to use is as
follows: 

-Updates are letters 'G', 'H' and 'I' below- 

A. User-Agent: 
Mozilla, Windows XP, 128-bit encryption, English
(non-localized), Firefox.

B. Referer(Referrer):
Is set to the root (home page) of the site you are
currently visiting
(eg."http://www.example-root.com";;).
   
I think it is wise to use {forge} for the template
Referer setting.  If we use a real domain with the
{custom} paramiter it may get Tor in trouble with the
real domain's owners.  I am pretty sure we can not use
{block} as it breakes many sites.

Note: 
HTTPS referrer from one HTTPS URL directly to another
HTTPS URL is set to {block} incase RegControl can not
properly handle these headers.  This is because I have
not tested (and I don't know) HTTPS to HTTPS referrer
headers.  

C. Keep-Alive:
Close

D. Compression:
Prevented

E. X-Forwarded-for:
Not removed or spoofed as FF does not have this
capibility.  Besides, the entry node removes your real
"X-Forwarded-for:" header and it already has your real
IP.

F. Ping:
FF will supress the Ping function in HTTP/S.

** G. Accept-Languages:
Configured to match the language in "User-Agent";
English non-localized (<en>).

H. Accept-Default:
Used a configuration that should allow all relevent
file types and is used by a wide range of people
already.  

I. Accept-Charsets:
Again, use of a general default setting <iso-8859-1>
and I also used the all parm {*}.
