  • Fingerprinting is a complex beast and nearly impossible protect against. RFP (created and upstreamed by Tor Browser) protects and normalizes most fingerprintable metrics (timezone, display viewport dimensions, user agent, audio devices, installed system languages/fonts, etc) to a stable value for each Firefox version. Canvas is the only metric which is randomized. The purpose of this is to create a shared stable browser fingerprint for all RFP users, creating a crowd for people to blend in with each other.

    While RFP is strong, its anti-fingerprinting strategy was created for Tor Browser, which users are not supposed to customize. The same can not be expected of all other Firefox users, resulting in most users being much easier to distinguish from each other. RFP also can cause some site breakage and doesnt offer a granular way to toggle specific features per website (eg. Canvas protections breaks your webcam in conference calls).

    There is no good solution. Best options are use Firefox (or a fork like Librewolf) for casual use, and Mullvad/Tor Browser for more critical situations. Always use uBlock Origin (except with Tor).

    On the Chromium-side, Cromite and Brave randomize some fingerprintable metrics, but they aren’t as exhaustive and aren’t upstreamed to Chromium (for obvious reasons).


  • Online tests of uniqueness are skewed by the population who uses them, aka privacy-conscious aren’t the typical user even if a dataset overrepresents.

    My point was introducing Canvas noise isnt going to make you less fingerprintable, actually quite the opposite. Firefox’s RFP is much better at normalizing fingerprintable metrics and is native. Canvas is one of many many other fingerprinting vectors.

    If you go the route of trying to protect against fingerprinting through randomization, use the extension JShelter which seems to do much more noise than Canvas blocker does. I am still very skeptical of it (and other anti-fingerprinting extensions) because of how complex fingerprinting is.

    Docker is good when combined with gVisor runtime for better isolation.

    What is gVisor?

    gVisor is an application kernel, written in memory safe Golang, that emulates most system calls and massively reduces the attack surface of the kernel. This is important since the host and guest share the same kernel, and Docker runs rootful. Root inside a Docker container is the same as root on the host, as long as a sandbox escape is used. This could arise if a container image requires unsafe permissions like Docker socket access. gVisor protects against privilege escalation by only using root at the start and never handing root over to the guest.

    Sydbox OCI runtime is also cool and faster than gVisor (both are quick)


  • In that case it is a ToS violation, not piracy. You aren’t paying anything, nor does google lose any money since they have been already paid. We would have to stretch the definition of piracy to include other ToS violations since it is not a financial lose.

    Let’s extend the scenario. If YouTube ToS required you to click every ad to use their service, would it be piracy if someone doesnt follow those instructions? I think it would be a ToS violation, but what damages could Google even seek?

    I hear people sometimes mention that “Google needs to pay somehow to keep YouTube running.” I have no sympathy for Google since they conspired to intentionally push out other video hosting platforms to create monopoly on the market. It is their own fault that videos aren’t more spread out among providers.

    How would you even pirate YouTube anyways?


  • I recommend Mull. It is security/privacy hardened Firefox and built by using Fennec as a base. Always use Fennec over Firefox because it removes telemetry, proprietary code, and strongly protects against browser fingerprinting. Comes with support for most (if not all) desktop Firefox extensions. I highly recommend using uBlock Origin, ask anyone and they’ll tell you it is the best content blocker available.

    Another good browser is Cromite. It is security hardened Chromium with built-in ad/content blocking, decent fingerprinting protection, and strong site isolation. It doesn’t have support for extensions because upstream Chromium on Android doesn’t either and it is hugely complex to port.
