As a side note, using Brave browser with all protections turned on by default, including Javascript disabled, and re-enabling Javascript (2 clicks) only on the websites you care and trust enough to, has made my Web browsing experience incredibly better, especially on mobile.
Now everything loads in an instant, no more shenanigans that jump around the screen as I scroll, no Facebook/Twitter/Google buttons (that nobody even uses), no pop-up/in/out/over adverts, and even those asinine cookie warnings are gone by default!
I cannot recommend it well enough.
I do the same on Firefox with Privacy Badger and Noscript extensions, supplemented with a PiHole on the network to disappear all those intrusive ads. On my phone, I use Naked Browser Pro, which lets you allow Javascript per site, along with Adaway.
> 25 third parties that know what you visited
Ever try running traceroute?
How is that relevant here? You mean that when I connect to A there will be some intermediate points, that is true but those points are not setup there to track me, some points will differ, there are protocols to work around tracking at that level(using proxies and VPNs). But if I don't block the tracking scripts and cookies and I have 2 tabs with 2 different sites and both have FB code in it, FB will know I am the same person, they will search in the shadow profiles, find me, add this extra data to the profile. Then 24 more trackers will do the same,
I can visit site A and B, not put any of my data intentionally on them but still my data get be funneled to 25 third parties that know what I visited.
So your point is don't use internet or turn of javascript and open each link in private windows and maybe use some proxyes or Tor
