Earlier quoted context omitted.
This statement is false. Even with all telemetry disabled (including the option "Allow Firefox to send technical and interaction data to Mozilla") and without anything showing on that page, the browser still sends out interaction data by means of so called "pings", URL parameters, etc.
Wow, a browser is making network connections, how dare it. Come on, these things are there so that if you are on "connected" to a network that require some registration, e.g. an airport, then you can actually be forwarded to that registration page. Like what do you even think, Mozilla people are sitting on top of all that sweet PING www.mozilla.org (3.161.119.172) 56(84) bytes of data. 64 bytes from server-3-161-119-…
Regardless:
The browser asks me if I allow it to make these connections.
I tell it in unmistakable and irrevocable terms that I do not.
The browser makes these connections anyway.
The problem was never the connections or the contents of the data stream. You were aware of this before posting your comment, and yet you commented anyway. You are a troll.
