- Avaliado em 5 de 5por Denis Kasak , há 7 anosPlease 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.Resposta do programador

publicado a há 7 anosA version for Opera or Chrome is not planned. They do not provide the necessary APIs to provide the same quality of protection. - Avaliado em 5 de 5por Utilizador do Firefox 14300424 , há 7 anosIt 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 - Avaliado em 5 de 5por Utilizador do Firefox 14097838 , há 7 anosA must have privacy extension for everyone!
- Avaliado em 5 de 5por Utilizador do Firefox 14242164 , há 7 anosGreat stuff. I think this should be a "featured extension" in the pivacy and security category.
- Avaliado em 5 de 5por Utilizador do Firefox 14054127 , há 7 anosNice, 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?Resposta do programador
publicado a há 7 anosThe color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - I 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.

- Avaliado em 5 de 5por Fleet Command , há 7 anosIt 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.

Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.Resposta do programador
publicado a há 7 anosI 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. - Avaliado em 5 de 5por Utilizador do Firefox 14156124 , há 7 anosNice 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):

publicado a há 7 anosGood 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.
