Subject: [FD] TOR browser / Firefox telemetry data

POC:

tl;dr

run just Firefox browser / TOR and just nothing

and tcpdump the computing device /  network

firewall BLOCK all IP/A names, gradually... that shows up in tcpdump
when you do not using firefox but it connects automatically (if you
block something firefox hops to something else, 3-5+ times )

QUICK FIX:

in address bar:

about:config
>>> then
search for string:

org

com

mozilla

firefox

google

...?

to start with : almost all... the url string that shows up in the
above search, should be removed in TOR and firefox browser or left to
minimum
---

after you fix it : see no activity in tcpdump when firefox is idle

Does everyone use their own customized OS/s now ?

Recommendation : firefox being a OSS browser, should create a master
switch for ... .

The corporate / world is going in the opposite direction, everyone
want a piece of everything

android/iOS seems as new windows 3.1

and then malware/RAT as now - games, apps, android, in every computing
device, every app.
