    This add-on needs instructions on how to use. If present already they need to be easier to find.

    Usually you install the addon, select a preset that matches your needs and you are good to go.

    Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with a description of what you want instructions for. There we can communicate better and you can follow the progress on the subject.

    Awesome. Works great. Thanks for the privacy policy that actually allows for... privacy!

    I downloaded this and it really blocked most of my sites and make a lot of other Firefox Icons stop working. I uninstalled it and everything is fine. My friend had the same thing happen. We both use the newest Firefox and windows 10. Thanks anyway but we will stay away from this add-on..

    I'm not sure what you exactly mean by "a lot of other Firefox Icons stop working" but it sounds like something I should look into. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with your specific problem and your settings.

    The blocking of sites is often something that can be addressed by settings. You can also open an issue for that and I can look what your sites need to work properly.

    really helped my online activities. its unimaginable how much the third party tracker want to track you. literally like "this is the user screen, right now. I want to know."

    Thanks for providing such a good add-on, which has been a great help to my life. Recently, firefox mobile version of a major update, many add-ons are no longer applicable, and your plug-in is my daily life is necessary, I beg you to adapt to the latest mobile version of the framework as soon as possible.

    Unfortunately there is nothing I can do about that. Mozilla dropped add-on support in Fenix except for some hand picked ones. CanvasBlocker is not part of that list (it is not "recommended" by Mozilla).

    It's up to Mozilla to decide on add-ons in Fenix: https://blog.mozilla.org/addons/2020/09/02/update-on-extension-support-in-the-new-firefox-for-android/

    Great lightweight extension that can help protect your privacy by giving randomised readouts when websites try to fingerprint you. Best used in conjuction with other privacy tweaks such as blocking third party cookies, and using an ad/tracker blocker like uBlock Origin.

    A good add-on with tons of settings, and information regarding them. Not a fan of the UI, though. The add-on window, only shows 5 options, and one search bar. I would like to see this expanded with more options relating to what's being blocked/altered (or is not), whitelisting, and so on. The main add-on Settings page also looks ugly, but at least it's functional.

    Overall, I would suggest this add-on to others. I found it does a better job than competition, which considering how much there is, is pretty impressive.

    You can find the information about what is blocked/faked in the page action menu by clicking on the fingerprint icon in the address bar.

    Whitelisting works, and even has 2 different kinds of whitelisting. The global one, as well as the one by API breakdown. Both need to be updated in terms of UI response and have a better and faster way of adding a website. No easy way to set a safe setting that *just works*, something always breaks and there's no easy "whitelist this specific breakage" button available.

    The whitelisting is working for me. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with your specific problem and your setting.

    I mostly use default settings and have no whitelist defined. Please also mention the web sites that break in your issue.

    How the whitelist button can be found is explained here for example: https://github.com/kkapsner/CanvasBlocker/issues/330

    PS: the UI is a topic I want to tackle in the near future.
