TMH #7: Browser Tracking Protections with Simo Ahava

Simo sits down with Simo again to deliver a solo episode. This time, we walk through browser tracking protections, what they are, and why should we care.

Once again flying solo, Simo Ahava discusses the phenomenon known as browser tracking protections in this short but topical episode.

Tracking protections are designed to prevent sites from tracking you – especially across the web but increasingly also while you are browsing the site itself.

The mechanisms deployed by browsers to tackle the problem of “tracking” (a loosely defined concept if there ever was one) are often quite brutish, resulting in web compatibility issues as well as limiting legitimate use cases for browser storage access.

Simo walks you through the difficult mess that tracking protections are, focusing mainly on Apple but devoting time to the other three browsers that also deploy tracking protection features. He also devotes some time to the one major browser that does not deploy any tracking protections at this time.
