    Very nice works.
    But it may not pass detective on test page http://101.37.204.139:8080/uapost.html.when try times test, it may enter an endless loop and Let the browser stop working.

    Nice works.
    Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.

    I know - this page is not written in a peformant way. You can test the audio fingerprint at http://kkapsner.github.io/CanvasBlocker/test/audioTest.html as well.

    Nice works.
    Please note it does not detect (and block) the code embedded in a url through the
    "data:text/html" directive.
    I don't know if this method it's exploitable in a web page

    example: paste the following code on your navigation bar
    (It's a dots wave single pixel plotter, so it uses getImageData and it works even if you block the readout API):

    edit: sample code moved to pastebin (sorry, pasting the code here does not works):

    Good point. I will see if this is exploitable. But please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss the implications and findings. Also communication is much easier there.

    Thank you for this extension (and for keeping it opensource). Nowadays it's getting harder and harder to get a sense of real privacy. CanvasBlocker + AdGuard for Windows + Privacy Badger + HTTPS Everywhere + custom user.js helps me feel safer on a growing data collection frenzy.

    100% unique mean that is not really natural, canvas should not be unique but changed in order to be natural.
    Unique canvas fingerprints will do much worse.
    Is like you said you have a device that never exist.

    To better understand how this work :
    Google already have a full database with all kind of canvas signatures from all worldwide devices (iphone, android, computers, etc...), and if your canvas signature will not match on them database then you fail, it is a prove that your canvas is fake. If you try to spoof the signature then image pixel parameters will not match and again you fail so is almoust imposible to pass canvas.

    On default settings may make it pass the google test.

    For example google will not ask for SMS confirmation when a new gmail account is created because he trust the device you use.

    Most of people must understand why unique signatures is bad practice and all softwares that spoof parameters will make traking services to detect the device much easy

    Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss this. AMOs rating comments are too limited to have a good conversation.

    One small comment on unique signatures: they are not bad by itself as long as they are not persistend (i.e. the timestamp you connect to the server is very likely to be a unique signature but it's not persistent). This is the case in the CB default settings.

    Can't seem to get version 0.4.4b working with Firefox ESR 52.7.2, there's just no icon visible anywhere on the UI.

    Edit: My bad! I remember that this addon had an icon before but nowadays it hasn't. Works great!

    This Addon does not have an icon that is always visible. Only a fingerprint icon is displayed in the adress bar when some canvas data was faked for the web page. You can test at http://kkapsner.github.io/CanvasBlocker/test/test.html

    If you still think that it's not working properly try version 0.4.4a and open a new issue at https://github.com/kkapsner/CanvasBlocker/issues

    EDIT: no problem. Glad that it works for you.
