It looks reasonable with their table. Not sure if I want to try it though, enabling a lot of the privacy features like resist fingerprinting often breaks login flows, and breaks dark mode detection on sites. It also does some stuff like disabling URL bar suggestions that really impacts usability.
Overall I’d say these things are only worth it if you don’t use your browser to do normal every day things like banking, shopping, and watching media.
Yeah and I wouldn’t mind if there was a button I could click to whitelist a domain from all the privacy protections, but FF doesnt have that.
