I turned on transparent proxying for HTTP and HTTPS the other day to see what requests FF was up to for its highlights on the supposedly blank page etc.
It's very chatty, annoyingly. Captive portal check on all requests that has to be disabled in about:config and a laundry list more. That config is scarily full of remote and telemetry based URLs also, but at least they are co figurable I guess.
An open source browser that just does what you want and no more seems like a dying hope.
