Firefox ユーザー 14156124 によるレビュー (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):

投稿日時: 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.

I will leave it on incase it is working. It would be better as an app to work all the time my device is on rather than just inside my browser.

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. - 5 段階中 5 の評価Firefox ユーザー 18642424 によるレビュー (25日前)

- 5 段階中 4 の評価AnoniM0US3 によるレビュー (2ヶ月前)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)
