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…
Because stock FF is full of telemetry and tracking.
(Librewolf and Mullvad have the best scores because they are just FF without all the garbage)
They are FF with the defaults set to “I don’t care if enabling this breaks my websites”.
Telemetry is personal preference. Sending that data to a company you trust to use it for the stated purpose (making Firefox better) is a choice, and FF lets you easily disable it.
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).
If you’re already used to running an assortment of privacy-oriented additions on another browser, librewolf breaks in familiar ways… but it still breaks.
For example?
Iunno, I fix and move on. Usually fields refusing to cooperate unless they phone home.
Never encountered that issue.
Fortunately it’s infrequent, but it’s still annoying to re-enter multiple fields because a connection couldn’t be made to a telemetry service.
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
