New browser tested with tcpdump: Konqueror
Settings used (listing only the ones different from the default values):
General
When Konqueror starts: Show blank page
Home page: about:blank
Performance

Java&JavaScript
Enable JavaScript globally: OFF
Cookies
Enable cookies: OFF
AdBlock filters
Enable filters: OFF
Result
On startup tcpdump shows nothing (zero packets sent).
Something strange happens though when opening a page. For example browse to
https://stallman.org shows lots of requests to amazonaws.com, flickr.com and
others which continue to appear even after the page is loaded. This makes me
think Javascript may not be actually turned off because in the page source
there are no any resources which need such lengthy extensive loading. tcpdump
shows such packets to continue for some time even after the browser is shut
down.
Also tested with https://stallman.org/robots.txt (to avoid any potential
script interference). Result: the extra packet traveling doesn't happen, i.e.
the document is loaded and everything stops.
