If this isn't a targetted advert in my browser, I don't know what is.

Can you expand on user.js.

Is that the arkenfox user profile? How do you upload it? How often is it updated?

Sure. User.js is a file you can add in your Firefox profile directory which gets loaded each time Firefox starts.

Pretty good documentation here: https://kb.mozillazine.org/User.js_file

The arkenfox one is a fully loaded pro-privacy user.js made by some knowledgeable people. I did use that one for my initial version iirc: https://github.com/arkenfox/user.js/blob/master/user.js

How often do I update it? Just when mozilla rolls out a new feature I don't like. I commit it to my repo, that way I easily take my settings to each different machine. You cannot change every FF setting with that file, but you can change the majority of them.

So two things: basically install user.js and forget it (except changing minor settings you want).

What about recommended extesnsions. It just says minimize extensions (which is a good policy), but which extensions are recommended to use with it.

Are there certain privacy extensions that are redundant because of it?

I understand I may be asking things outside of your purview, but I am curious how does this work.

Interesting enough, if I visit a fingerprinting site such as kuber.studio/cookie, it still recognizes me as a visitor, even with user.js.

Yeah, I'm not a privacy expert. And I didn't ever think of user.js as privacy protection personally. I use it to turn off AI and other things that annoy me. Privacy-wise I use OBO and few others. The arkenfox settings I used as a basis but I removed anything that wasn't ai related or that I didn't understand.

I think the main protection I'm looking for at the moment is fingerprinting protection. ON their site they do claim that, but there isn't much info (at least that I can understand about that).

Okay, that is a different topic in my mind. User.js is about settings. The settings it impacts can be anything. You may want to try librewolf if privacy is your focus.
