Ответ разработчика
размещено 8 лет назадA version for Opera or Chrome is not planned. They do not provide the necessary APIs to provide the same quality of protection. - Оценено на 5 из 5от Darsh229, 8 лет назад

размещено 8 лет назадPlease open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details and a reproduction scenario. There we can communicate way better. - Оценено на 3 из 5от Пользователь Firefox 13268901, 8 лет назадWhat 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?
Ответ разработчика
размещено 8 лет назадThe 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 - Оценено на 5 из 5от Пользователь Firefox 14097838, 8 лет назадA must have privacy extension for everyone!

размещено 8 лет назадTell me what you dislike about the new version. Without this information I cannot improve CB. - Оценено на 5 из 5от Пользователь Firefox 14242164, 8 лет назадGreat stuff. I think this should be a "featured extension" in the pivacy and security category.
- Оценено на 5 из 5от Пользователь Firefox 14054127, 8 лет назадNice, 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?Ответ разработчика
размещено 8 лет назадThe color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - Оценено на 5 из 5от Detergent, 8 лет назадI 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.

- Оценено на 5 из 5от Fleet Command, 8 лет назадIt 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.Ответ разработчика
размещено 8 лет назадThis page doen't even work when no addon at all is installed... but to discuss this further please open an issue at https://github.com/kkapsner/CanvasBlocker/issues
Communication is much easier there. - Оценено на 5 из 5от zhaqenl, 8 лет назад

Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.Ответ разработчика
размещено 8 лет назадI 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. - Оценено на 5 из 5от Пользователь Firefox 14156124, 8 лет назадNice 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/pFvdgKNNОтвет разработчика
размещено 8 лет назадGood 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. - Оценено на 5 из 5от GregDT, 8 лет назад

Does it make problems with twitter header image upload?
i got probsОтвет разработчика
размещено 8 лет назадYou 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.
