Data: 8 lat temuPlease open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details and a reproduction scenario. There we can communicate way better. - Ocena: 3/5Autor: Użytkownik Firefoksa 13268901, 8 lat temuWhat happened to the fingerprint icon up in the toolbar on android FF? It is now gone so how do I know if CB is functioning correctly?
Odpowiedź autora
Data: 8 lat temuThe fingerprint icon should be present if you have notifications enabled and something was faked on the page.
You can check if CB is working on the test pages (e.g. https://canvasblocker.kkapsner.de/test/test.html - the hashes should change on reload).
Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues - there we can discuss better.

Data: 8 lat temuTell me what you dislike about the new version. Without this information I cannot improve CB. - Ocena: 5/5Autor: Użytkownik Firefoksa 14242164, 8 lat temuGreat stuff. I think this should be a "featured extension" in the pivacy and security category.
- Ocena: 5/5Autor: Użytkownik Firefoksa 14054127, 8 lat temuNice, 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?Odpowiedź autora
Data: 8 lat temuThe color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - Ocena: 5/5Autor: Detergent, 8 lat temuI 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.

- Ocena: 5/5Autor: Fleet Command, 8 lat temuIt 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.Odpowiedź autora

- Ocena: 5/5Autor: The Beard Below My Chin, 8 lat temuNice works.
Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.Odpowiedź autora
Data: 8 lat temuI 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. - Ocena: 5/5Autor: Użytkownik Firefoksa 14156124, 8 lat temuNice 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):

Data: 8 lat temuGood 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. - Ocena: 5/5Autor: GregDT, 8 lat temu
- Ocena: 3/5Autor: Clemens Ratte-Polle, 8 lat temuWhere can i test the success of CanvasBlocker?
Does it make problems with twitter header image upload?
i got probsOdpowiedź autora
Data: 8 lat temuYou can go to http://kkapsner.github.io/CanvasBlocker/test/test.html and check if the displayed hash changes on every reload.
I know of no problems with twitter. But if you think that it is CB related please open an issue at https://github.com/kkapsner/CanvasBlocker/issues - there we can communicate much better. - Ocena: 4/5Autor: Jezze, 8 lat temuDoesn't make my canvas fingerprint less unique. amiunique.org still tells me that my similarity ratio is below 0.1% which means I have a very unique canvas fingerprint.
Odpowiedź autora
Data: 8 lat temuIn the default settings the canvas fingerprint is changed on every page reload (you can test that on http://kkapsner.github.io/CanvasBlocker/test/test.html). Yes - this makes the fingerprint unique but since it is not constant you cannot be tracked.
If you want further information/discussion please open an issue on https://github.com/kkapsner/CanvasBlocker/issues where we can communicate nmuch easier.
