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 haven’t experienced any website breakage with Librewolf. Mullvad breaks websites because it has noscript by default (even though uBlock Origin has noscript built in).
Then that’s my point illustrated. It’s easy to make a browser 100% secure, you just take it off the Internet.
The middle ground is the hard part. Supporting both is the hard part
