We are always trying to understand how we can better control our privacy on the internet, and your choice web browser to use is among the most important decisions you can make. We used EFF's "Cover your tracks" website (https://coveryourtracks.eff.org) to compare six different well-known browsers for web tracking and browser fingerprinting.

Tor browser apparently provided the strongest protection against web tracking and contained fingerprinting uniqueness to 1 in about 46k. They try to provide a uniform fingerprint across devices, allow you to hide in a crowd. Brave, on the other hand, takes a different approach. While they provided only some protection against web tracking, but they constantly randomize the fingerprint, providing "very strong" protection against indentification through fingerprinting. We arranged the results in the order that we perceived each browser's privacy benefits.

There was no discernable privacy protection at all with Chrome and Edge browsers.
