Didn't even know I need it until a web page started to abuse canvas to shove ads in your face - 评分 3 / 5来自 Firefox 用户 13268901,6 年前What 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?
开发者回应
发布于 6 年前The 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 - 评分 5 / 5来自 Firefox 用户 14242164,6 年前Great stuff. I think this should be a "featured extension" in the pivacy and security category.
- 评分 5 / 5来自 Firefox 用户 14054127,6 年前Nice, 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?开发者回应
发布于 6 年前The color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - 评分 5 / 5来自 Detergent,6 年前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.

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.开发者回应
发布于 6 年前This 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

Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.开发者回应
发布于 6 年前I 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. - 评分 5 / 5来自 Firefox 用户 14156124,6 年前Nice 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):

发布于 6 年前Good 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. - 评分 5 / 5来自 GregDT,6 年前

Does it make problems with twitter header image upload?
i got probs开发者回应
发布于 6 年前You 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. - 评分 4 / 5来自 Jezze,6 年前Doesn'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.
开发者回应
发布于 6 年前In 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.
