> Canvas-based fingerprinting due to rendering differences is a thing, so using the canvas is not pixel-perfect either Luckily Firefox asks you if you want to use the HTML5 canvas API. You can specifically whitelist some pages to use the canvas API and stop it from running by default on all your other browsing. Also: you may want a dedicated browser just for Google's whole ecosystem so they can't track you across the web. I have a Chromebook just for that, which has its own unique canvas fingerprint completely separated from my main workstation PC's fingerprint.

> Luckily Firefox asks you if you want to use the HTML5 canvas API. Really? Where? I know you can disable it in about:config, but not that it was asked of the user. I have used Nightly for years and never seen such a dialog. Unless you did mean about:config, but I don't know how that works with a whitelist either.
