Mozilla is introducing a new feature to Firefox aimed at protecting users from bounce trackers, the browser developer has announced. Bounce tracking is a technique where a user clicks a link but ends up reaching their intended destination via an intermediary tracking page. This allows trackers to place and read 'first-party cookies,' which aren’t blocked by the browser, unlike third-party
It could only know that by navigating to the link in the background. That would have side effects, like them being able to track you even when you don’t click on links.
Fine! If there’s Javascript fuckery going on, then the status line should say “WARNING: JAVASCRIPT FUCKERY!”
If the link is to a redirector then that’s what should show in the status line.
I don’t pretend to know how any of this works, but the link is obviously already there in the browser, otherwise it couldn’t direct you to it.
But it doesn’t always point to the destination. Instead, it points to another page that then redirects you to the destination.
Your browser does not know the address of the destination, only the addresss of the middleman tracking webpage.
