Remember that trying to make a browser like Chromium or Firefox hard to fingerprint is harder than it seems.<p>There's <i>a lot</i> of stuff you need to change, including fonts, screen resolution, system memory, user agent details (some browsers also add Sec-CH-UA strings), timezone, along with things like WebGL fingerprinting etc<p>It's also worth noting that you can sometimes actually make yourself <i>more</i> fingerprintable by not properly hiding something, like changing your UA in HTTP requests but not in JavaScript as well. If a website detects such a "quirk", it would be able to fingerprint you with a lot more precision.<p>TL;DR If you really want to stay anonymous and not worry about fingerprinting and trackers — use Tor Browser. It was specifically designed so that everyone has the same fingerprint, and has things like letterboxing to hide resolution etc. It's unlikely you'd be able to do a better job than Tor Browser by modifying your own browser.
