One of the less known features of Internet Explorer 9, released way back in 2011, was its Tracking Protection. In it, there was an option to turn on personalized tracking protection where it heuristically keep track of trackers that appear more than once on different sites and block it automatically. You can still find it in Internet Explorer 11. And prior, IE8 had a lot of features that was ahead of its time. IIRC, IE8 was one of the first browsers to have ad-blocker built in. This was almost a decade before any other browser made tracking protection a built in feature.
I would like to see Mozilla Firefox be forced to do the same. As of now, they don't even notify the user of their default Google search to the users. So millions of their user url typing history are being recorded and sent to Google even if they don't use the search function specifically. This in someway has to violates the GDPR.
