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):

objavljeno ob pred 7 letiGood 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.
