    Overall works well BUT, when protecting Navigator (choosing a different OS or browser, any of the 2) it is caught by https://iphey.com/

    Navigator protection is always tricky and you cannot hide it completely. But if I choose a different OS it does not get caught by this page. Maybe there is something additional that causes that in your setup.

    Sometimes consumes up to 100 megabytes memory.

    Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with your details. This should not happen and I do not see a massive memory consumption.

    It broke Google

    Edit: Okay, thank you.

    Please revert to version 1.9 - version 1.10.1 is in the works.

    See https://github.com/kkapsner/CanvasBlocker/issues/699 and https://github.com/kkapsner/CanvasBlocker/issues/700 for the progress of the solution.

    This particular extension draws too much power from my laptop. Otherwise it is working incredibly well.

    not perfect, but it helps, especially if it is used with other addons, it still doesn't randomize your fingerprint like BRAVE does, only BRAVE gets 3 yes's on EFF's 'cover your tracks' (Ads, Trackers, Fingerprints), or, this addon, with Ublock Origin, Privacy Badger, Local CDN and NoScript (is what I use on Librewolf) gets you all 3 yes's on EFF (1 in 900, so 'common as muck' fingerprint, and unable to track & trace through fingerprinting)

    On coveryourtracks.eff.org shows "Your browser has a unique fingerprint" with a red line under it, And on the section of hash it shows "randomized by first party domain", So I guess it is working some way.

    Caused massive slow down when using ebay and other websites. Firefox identified it as causing slow down, task manager showed as 30% cpu usage for FF.

    There is little I can do about the problem with eBay. Whitelisting the DOMRect-API helps:
    https://github.com/kkapsner/CanvasBlocker/issues/555
    https://github.com/kkapsner/CanvasBlocker/issues/563

    That's why it's whitelisted in the convenience preset.
