- Noté 5 sur 5par Denis Kasak, il y a 7 ansPlease consider adding an UI element for adding/removing the site from the whitelist without having to manually edit the string in the settings. 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.Réponse du développeur
mis en ligne : il y a 7 ansThis is already implemented. See my comment on https://github.com/kkapsner/CanvasBlocker/issues/285 - Noté 5 sur 5par JanKKM, il y a 7 ansThe addon works perfectly. I tested all extensions for blocking canvas and this one definitely does the best job.

mis en ligne : il y a 7 ansA version for Opera or Chrome is not planned. They do not provide the necessary APIs to provide the same quality of protection. - Noté 5 sur 5par Darsh229, il y a 7 ans
- Noté 5 sur 5par Utilisateur ou utilisatrice 14300424 de Firefox, il y a 7 ansIt 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 - Noté 5 sur 5par Utilisateur ou utilisatrice 14097838 de Firefox, il y a 7 ansA must have privacy extension for everyone!
- Noté 5 sur 5par Utilisateur ou utilisatrice 14242164 de Firefox, il y a 7 ansGreat stuff. I think this should be a "featured extension" in the pivacy and security category.
- Noté 5 sur 5par Utilisateur ou utilisatrice 14054127 de Firefox, il y a 7 ansNice, but the toolbar icon changes color sometimes (red/green). What do the different colors mean?
Green = I'm save, red = I'm not protected? And what do I have to do for it to protect me again?Réponse du développeur
mis en ligne : il y a 7 ansThe color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - Noté 5 sur 5par Detergent, il y a 7 ansI tested this addon with the Panopticlick test from the EFF, and when I check the 'full results' it shows that the hash values are changed every time I have the addon enabled. So I guess it's basically ruining it for people who use these values to track you.

- Noté 5 sur 5par Fleet Command, il y a 7 ansIt is great, but it'd be much better if the Mozilla Add-ons link embedded in it was language-agnostic. Currently, it is to the German version of the site.

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.Réponse du développeur

Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.Réponse du développeur
mis en ligne : il y a 7 ansI 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. - Noté 5 sur 5par Utilisateur ou utilisatrice 14156124 de Firefox, il y a 7 ansNice 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):

mis en ligne : il y a 7 ansGood 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. - Noté 5 sur 5par GregDT, il y a 7 ans
