google cookie

["Karsten N." <tor-admin@xxxxxxxxxxxxxxxxxxxx>]

Hi,

I have a question about google cookies and tor hidden services.

I use a Firefox with a separate profile for tor (Iceweasel Debian
5.0/lenny). I have installed the add-ons TorButton 1.2.1, CookieSafe
and RefControl from the Mozilla website.
Update of add-ons and search plug-ins is disabled.

On normal startup Tor is activated and never disabled. And I use this
firefox profile only for access tor hidden services.

And I got cookies from google.com!

Is it possible? I can not believe it. It is not a problem for me, I
can disable cookies. But it is interesting.

I checked it with two tor hidden services. I am sure, the hidden
services do not send a cookie and do not cooperate with google.com.
The cookies were not send at the index page, they were placed at the
2-3 access the hidden service.

Any help, how this works?
