I have been doing fingerprint research for several years. I’ve done countless builds with various browsers, configurations, extensions, and strategies. (Yes i have too much time for this).
Here is what I’ve concluded. I hope this helps someone.
CoverYourTrack is crap, plain and simple. Your best option will always be to randomize. Always. You will not “blend in”. I don’t care if you run Google Chrome on Windows 10 or Safari on iOS, JavaScript exposes way too much info, you will always have a unique fingeprint. Just go play around with fingerprint.com on some normie browser/os setups and you will see what i mean.
You must randomize all the values that you see on sites like browserleaks.com. canvas, audio context, webgl hash, clientrects, fonts, etc etc. I’d also make sure you are proxifying all your browsers and using random locations. You can do this with Brave somewhat, which has some randomization stuff in it. You can do this with browser extensions as well. Ungoogled chromium also has some randomization for canvas and clientrects i think
There are only a couple options outside of this that I recommend, in the realm of “generic fingerprint” solutions. TOR browser (they have been on the front lines of this for many years). And also Mullvad browser, which, despite its generic fingerprint goal, seems to also defeat fingerprint.com.
Tldr, if you want the best experience out of the box that is also very usable, just use Mullvad Browser. They are basically the browser i wished for for like a decade.
