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.開發者回應

張貼於 7 年前A version for Opera or Chrome is not planned. They do not provide the necessary APIs to provide the same quality of protection. - 評價 5 分，滿分 5 分來自 Firefox 使用者 14300424，7 年前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 - 評價 5 分，滿分 5 分來自 Firefox 使用者 14242164，7 年前Great stuff. I think this should be a "featured extension" in the pivacy and security category.

Green = I'm save, red = I'm not protected? And what do I have to do for it to protect me again?開發者回應
張貼於 7 年前The color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - 評價 5 分，滿分 5 分來自 samyueru_beityosef_benmayumi，7 年前

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.開發者回應

Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.開發者回應
張貼於 7 年前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. - 評價 5 分，滿分 5 分來自 Firefox 使用者 14156124，7 年前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):

張貼於 7 年前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.
