Based on https://privacytests.org
Desktop browsers in their current stable versions, sorted from better (left) to worse (right). These are:
Librewolf, Mullvad, Brave, Tor, Safari, Chromium/Ungoogled, Firefox, Edge, Opera, Vivaldi, Chrome.
Note: Each test is counted with a value of one in this chart, however each test may not have an equal importance in regard to privacy. It still gives an image of which browsers value privacy and which do not.
The maximum (worst possible) score is 143.
Edit: Also FUCK BRAVE. But for other reasons than these points. Read the description before you vote or comment ffs…
I can guarantee you it is not a “Brave ad” (again, sigh), I am a Firefox user which found this website with a bunch of tests. I am not claiming it is perfect, the best thing would be able to weigh different tests based on importance. But I am not aware of any website with more accurate data. Do you a link to one? I’d be happy to make another, better one.
