    Works, but slows some sites to a crawl (i.e., eBay). Settings are hard to understand. Unclear how to whitelist a site.

    For eBay you can check the discussion on https://github.com/kkapsner/CanvasBlocker/issues/555 and https://github.com/kkapsner/CanvasBlocker/issues/563

    The best way to whitelist a site is over the little fingerprint icon in the URL bar.

    Optimizing the settings is on my todo but it's hard as I'm not a UX/UI person...

    На насыщенных страницах типа youtube, google docs вызывает перманентное повышенное потребление процессора

    I assume you meant CanvasBlocker with "google docs"...
    You should check which API protection is causing the CPU usage and consider allowing this API on these sites. Also ignoring the DOMRect API in the notifications (you have to enable the expert mode to be able to do that) can help massively with performance problems.
