- Hodnotenie: 3 z 5autor: Používateľ Firefoxu - 13268901, pred 7 rokmiWhat 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?
Odpoveď od vývojára
uverejnené pred 7 rokmiThe 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 - Hodnotenie: 5 z 5autor: Používateľ Firefoxu - 14097838, pred 7 rokmiA must have privacy extension for everyone!

uverejnené pred 7 rokmiTell me what you dislike about the new version. Without this information I cannot improve CB. - Hodnotenie: 5 z 5autor: Používateľ Firefoxu - 14242164, pred 7 rokmiGreat stuff. I think this should be a "featured extension" in the pivacy and security category.
- Hodnotenie: 5 z 5autor: Používateľ Firefoxu - 14054127, pred 7 rokmiNice, 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?Odpoveď od vývojára
uverejnené pred 7 rokmiThe color change just indicate that something was faked. It's some sort of notification and nothing to worry about. - Hodnotenie: 5 z 5autor: Detergent, pred 7 rokmiI 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.

- Hodnotenie: 5 z 5autor: Fleet Command, pred 7 rokmiIt 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.Odpoveď od vývojára
uverejnené pred 7 rokmiThis 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

- Hodnotenie: 5 z 5autor: The Beard Below My Chin, pred 7 rokmiNice works.
Please note I test the audio fingerprint at https://audiofingerprint.openwpm.com/ and it causes browser slowdown.Odpoveď od vývojára
uverejnené pred 7 rokmiI 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. - Hodnotenie: 5 z 5autor: Používateľ Firefoxu - 14156124, pred 7 rokmiNice 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):

uverejnené pred 7 rokmiGood 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. - Hodnotenie: 5 z 5autor: GregDT, pred 7 rokmi
- Hodnotenie: 3 z 5autor: Clemens Ratte-Polle, pred 7 rokmiWhere can i test the success of CanvasBlocker?
Does it make problems with twitter header image upload?
i got probsOdpoveď od vývojára
uverejnené pred 7 rokmiYou 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. - Hodnotenie: 4 z 5autor: Jezze, pred 7 rokmiDoesn'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.
Odpoveď od vývojára
uverejnené pred 7 rokmiIn 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 - Hodnotenie: 5 z 5autor: Používateľ Firefoxu - 13835690, pred 7 rokmiThank 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.

uverejnené pred 7 rokmiPlease provide a reason why you gave one star. Maybe I can fix the issue or improve CB with your input. - Hodnotenie: 3 z 5autor: Používateľ Firefoxu - 14072583, pred 7 rokmiDoes not work according to fingerprint test at https://panopticlick.eff.org/
