Unique properties and realtime entry-exit check

["Total Privacy" <nosnoops@xxxxxxxxxxx>]

Hi or-talkers, 
yet another issue concerning "without Tor" vs "with Tor". 


Two hypothetical examples: 

1. 
I´m using the normal Firefox (without Tor) with cookies enabled 
to log in on Yahoo email to make some stuff as my real identity. 
Then I close the normal Firefox and start Torpark Firefox with 
cookies enabled to log in on another Yahoo email to make some 
stuff as an fake identity. Now the question is, are the cookies 
capable to retrieve some unique information about my computer, 
that later is comparable at Yahoo head quarter, to figure out 
this two different Yahoo webmail accounts was actually runned 
from one same computer? 

2. 
The same base as in the example 1 above, but with the difference 
that no cookies enabled anywhere and the webmail account is at 
Fastmail with complete https connection for everything. Now the 
question is, are there some unique properties by my computer´s 
https handling that appear the same on the Fastmail head quarter 
to make sure the two webmail accounts was runned from the one 
same computer? 

In neither of the 1 or 2 above, is java, script or images enabled. 
BTW, I´m not asking to do some criminality, just for curiosity :) 


To go in the same post... 
It would be nice to have something att the bottom of browser window 
(only a thin line, perhaps in the Firefox status field) that on the 
left hand show the IP and country of at the moment active entry node 
and on the right hand (in the same line) have the IP and country of 
at the moment active exit node in the circuit. This line should be 
in realtime refreshing, one saple at second or 5 second or something.
