You do not need to rummage in about:config, there is literally a checkbox for it in settings. Maybe this was not the case when you tried it, I don’t know.

If you’re talking about Librewolf’s “resist fingerprinting”:

1. That is done for a very good reason (unfortunately, it’s not Librewolf’s fault that most websites are assholes and have found ways to uniquely identify every individual on every system)
2. You can very, very easily turn it off per-site, or browser-wide, or it has many configuration options in-between if it really bothers you that much.

So they’ve been working together and planning all this shit for at least 20 years, you think? *idly sharpens guillotine*

proton and wine run pretty much everything out of the box. It takes a little bit of figuring out how to run them. If you want to make it seamless and hate the command line, then it’s potentially somewhat more work.
