Greetings,
I have recently noticed that even the simple "offline" activities in TB
mentioned above initiate some kind of network traffic. I unfortunately do
not know how to see the specific contents of this traffic, but it is
definitively there as I have viewed it from the activity of the FoxyProxy
Add-On which I am using for a unique use-case. Regardless of the Add-On
being outside TBB's scope, I believe that this is an issue that affects
all Tor Browser users.
Leaking traffic like this assists with fingerprinting users and improves
correlation/timing-style attacks. It is also possible that some kind of
tracking cookie or other information is exchanged in this traffic, see
#5816.
It would be good to know what is in this traffic, and furthermore, to
disable this activity from a simple "offline" focus of the search box.
Thank you.
