  • Is it possible to add system fonts list faking?

    Unfortunately this is not possible. See the discussion at https://github.com/kkapsner/CanvasBlocker/issues/200
  • Единственное нормальное расширение в своем роде
  • The best!
  • Хорошее и полезное расширение. В версии 0.5.5 устранили баг и теперь всё Ок.
  • Please consider adding an UI element for adding/removing the site from the whitelist without having to manually edit the string in the settings. This UI should appear in the popup menu when the extension icon is clicked. This extension would be much more usable with this.

    UPDATE: This is great! As I mentioned on Github, I missed this because I'm not used to paying close attention to the icons in the address bar often since I'm using Tridactyl. I've updated my rating accordingly.
    This is already implemented. See my comment on https://github.com/kkapsner/CanvasBlocker/issues/285
  • The addon works perfectly. I tested all extensions for blocking canvas and this one definitely does the best job.
  • Hello, excellent program, for when a version for the Opera browser ??????
    A version for Opera or Chrome is not planned. They do not provide the necessary APIs to provide the same quality of protection.
  • It gets the job done.
    Didn't even know I need it until a web page started to abuse canvas to shove ads in your face
  • breaks webpages that require adobe flash on waterfox latest release
    Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details and a reproduction scenario. There we can communicate way better.
  • What happened to the fingerprint icon up in the toolbar on android FF? It is now gone so how do I know if CB is functioning correctly?
    The fingerprint icon should be present if you have notifications enabled and something was faked on the page.

    You can check if CB is working on the test pages (e.g. https://canvasblocker.kkapsner.de/test/test.html - the hashes should change on reload).

    Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues - there we can discuss better.

    This issue is solved in 0.5.5
  • A must have privacy extension for everyone!
  • Tell me what you dislike about the new version. Without this information I cannot improve CB.
