    I’ve got really good scores. I’m grading a bit on a curve due to mitigations/spoofs already in place for both browsers that fool the scripts effectively.

    4.45 bits from Firefox. [“System Fonts” is the worst score]

    4.47 bits from LibreWolf. [“AudioContext Fingerprint” is the worst score

    Some Measurements are Ignored; reasons within.

    User Agent - Flawed. This contains no personally identifiable information and spoofing this often causes compatibility and functionality issues. It is OK to spoof for -MORE- functionality if needed.

    WebGL Vendor & Renderer - Spoofed/Blocked Firefox spoofs this via CanvasBlocker and LibreWolf blocks this from being accessed at all. Spoofing allows some websites to feel “satisfied” they have some fingerprint that is otherwise patent nonsense and CanvasBlocker will present the same value to the website/script later if it’s loaded in the same Container/Context.

    Screen Size and Color Depth - Spoofed/Blocked Both Firefox and LibreWolf will spoof/randomize/standardize these viewport values back to scripts to preserve privacy. For functionality reasons my LibreWolf installation is my minimal plugin environment. This allows me to quickly and temporarily load a website I might NEED to use without compromising on Privacy while not being forced to troubleshoot which plugins might be preventing the site from loading in Firefox.

    System Fonts - LibreWolf Only Spoofed/Blocked Value is Randomized
