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.

An sich ein wirklich klasse AddOn, was Webseiten definitiv zu schaffen macht.
Leider bremmst es den Browser je nach Seite extrem aus.
Gerade Karten-Webseiten wie z.B. Google Maps sind teilweise unbenutzbar, wenn der CanvasBlocker zuschlägt.

Der Blocker von Firefox selbst, ist hier etwas harmloser, dafür aber auch von der Block-Qualität schlechter.

This is a game changer. This security add-on compliments your VPN and enhances the security of your web surfing experience. You should include this as one part of your layered strategy security plan.

its good but it would be great if right-clicking on the extension also had an option to temporarily disable it for testing purposes

I love this extension! However its a bit hard to use, because you have to uninstall, and reinstall the extension to open up the easy to use settings picker. If you change your settings as often as I do, if not then this is an easy 5/5 extension.

the addon prevents "youtube comment search" addon from working

is there a way to fix this, without having to turn canvasblocker off each time?

or even better: can i block or unblock each element separately, until i find the culprit? (the way "NoScript" addon visualized this is very beginner userfriendly)

thank you
