It is now gone so how do I know if CB is functioning correctly?
Resposta do programador
publicado a há 7 anosThe 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.
This issue is solved in 0.5.5 - 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.

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.Resposta do programador

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):
https://pastebin.com/pFvdgKNNResposta do programador
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. - Avaliado em 3 de 5por Clemens Ratte-Polle , há 7 anosWhere can i test the success of CanvasBlocker?
Does it make problems with twitter header image upload?
i got probsResposta do programador
publicado a há 7 anosYou 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. Resposta do programador
publicado a há 7 anosIn 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.
PS: similar issue on github: https://github.com/kkapsner/CanvasBlocker/issues/154- Avaliado em 5 de 5por Utilizador do Firefox 13835690 , há 7 anosThank you for this extension (and for keeping it opensource). Nowadays it's getting harder and harder to get a sense of real privacy. CanvasBlocker + AdGuard for Windows + Privacy Badger + HTTPS Everywhere + custom user.js helps me feel safer on a growing data collection frenzy.
