Canvas Path Support #5

Closed evdw87 closed 10 years ago

evdw87 commented 10 years ago

I like to notify you about the fact that www.html5test.com reports Canvas Path Support is enabled when using Canvas Blocker. This can be switched on/off with "canvas.path.enabled". I was wondering if you overlooked it or if it's on purpose.

Thank you for the notification.

This was not on purpose but it was not overlooked as well. It's not the aim of the Addon to remove the API but to block it. Therefore it will still be there but useless for fingerprinting.

I recently even added an option where the canvas-API can still be used to display things but the content can not be read so no fingerprinting is possible.

I just want to mention that the test on the mentioned site for the Canvas Path is only for existence not for functionality.
