AmIUnique VS user.js

I go the opposite way. I trust a company that takes my money to pay its costs to keep my privacy. As opposed to a company who "doesn't know who I am". (Apart from unique fingerprint https://amiunique.org/ over many queries over many months)

You're not completely wrong, but that ship has sailed a long time ago: https://amiunique.org

Until browser fingerprinting is addressed, there will be no real privacy.

You are. Compare the fingerprints of your two browsers: https://amiunique.org, https://coveryourtracks.eff.org. Very likely, the fingerprints are very similar. For anonymity, use Tor.

Browser Fingerprint Checker

Guarda qua: https://amiunique.org/

It’s mostly client-side stuff, you can access browser’s properties like canvas size, plugins, hardware, sensors. Try visiting https://amiunique.org/ You’ll get the idea.

Re: firefox and privacy, if you want to use firefox for privacy, consider using https://github.com/arkenfox/user.js . There is a case to be made that Firefox (with arkenfox's user.js) is one of the best privacy-respecting but still fairly usable browsers.

For extensions, I recommend people follow the recommendations[1] in the arkenfox repo and either harden their firefox or use librewolf. Umatrix is unmaintained since 2019.

For macOS : Thunderbird and you can harden it even more with this : https://github.com/arkenfox/user.js

only arkenfox

This article is shit. https://github.com/arkenfox/user.js/ is what you want.

If you make time to dig through settings and change them away from their official use (99% of users don't), then you should use a customized setup (in this case, a user.js). That way, you're good to go no matter what Firefox fork you use.

> Firefox remains a stable option to come back to everytime

Don't get me wrong, I've been using Firefox for the last decade and I don't intend on using anything else for the foreseeable future, but Mozilla has no idea what they're doing with Firefox nowadays. Firefox View is the most useless thing I've ever seen, that expiring "independent voices" theme picker was some weird hippie stunt[1], the latest UI redesign which split the tab from the window looks hideous, and it's not like Firefox doesn't have things you can tweak for a more private experience[2]. I miss Firefox Test Pilot where they tried out different new features, I found a lot of them to be very useful but sadly lots of them didn't make it.

Like others have said you can customize the browser to the point that it doesn't even look like the default anymore. Or customize it to maximize privacy.
