i gave up on firefox when i couldn't stop it from connecting to Google on a network device i was working on. Removing all the links from the advanced settings made it fail to start. That's when I realized how hypocritical they are. ( arm64 firefox-esr.) Even the latest chromium on arm64 connects to Google almost daily. i use epiphany-browser for that project now. no unwanted internet traffic from epiphany.
