8년 전에 게시됨Please provide a reason why you gave one star. Maybe I can fix the issue or improve CB with your input. - 5점 만점에 3점Firefox 사용자 14072583 님, 8년 전Does not work according to fingerprint test at https://panopticlick.eff.org/

8년 전에 게시됨What do you mean with "does not work"? Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can communicate better and therefore I can help better. - 100% unique mean that is not really natural, canvas should not be unique but changed in order to be natural.
Unique canvas fingerprints will do much worse.
Is like you said you have a device that never exist.
To better understand how this work :
Google already have a full database with all kind of canvas signatures from all worldwide devices (iphone, android, computers, etc...), and if your canvas signature will not match on them database then you fail, it is a prove that your canvas is fake. If you try to spoof the signature then image pixel parameters will not match and again you fail so is almoust imposible to pass canvas.
On default settings may make it pass the google test.
For example google will not ask for SMS confirmation when a new gmail account is created because he trust the device you use.
Most of people must understand why unique signatures is bad practice and all softwares that spoof parameters will make traking services to detect the device much easy개발자 답글
8년 전에 게시됨Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss this. AMOs rating comments are too limited to have a good conversation.
One small comment on unique signatures: they are not bad by itself as long as they are not persistend (i.e. the timestamp you connect to the server is very likely to be a unique signature but it's not persistent). This is the case in the CB default settings. - 5점 만점에 5점Firefox 사용자 14039775 님, 8년 전

8년 전에 게시됨This Addon does not have an icon that is always visible. Only a fingerprint icon is displayed in the adress bar when some canvas data was faked for the web page. You can test at http://kkapsner.github.io/CanvasBlocker/test/test.html
If you still think that it's not working properly try version 0.4.4a and open a new issue at https://github.com/kkapsner/CanvasBlocker/issues
EDIT: no problem. Glad that it works for you.- 5점 만점에 5점Firefox 사용자 13870378 님, 8년 전

개발자 답글
8년 전에 게시됨Yes, in the standard settings of CB the fingerprint that is produced with CB is quite unique but not persistent. That means the browser itself (and therefore you) cannot be indentified by it. (The same issue was reportet on github: https://github.com/kkapsner/CanvasBlocker/issues/154 - if you want further informations you can explore the issues there or post a new one.)
Also there are a lot of options which change the behaviour of CB (just mark the expert mode). If you want a less unique fingerprint you can use the "white" random number generator which will result in fingerprints similar to those of the Tor browser. - 5점 만점에 5점containers-everywhere 님, 8년 전

8년 전에 게시됨I do not see any errors. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where you can describe the scenario when you see the errors. 개발자 답글
8년 전에 게시됨I currently face weird problems. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details (versions, settings, etc.) so that I can find the root cause.
EDIT: please try version 0.4.4- 5점 만점에 2점Fred Thompson 님, 8년 전Description claims there is a whitelist option but...there is no visible way to see, let alone edit, such a list.
개발자 답글
8년 전에 게시됨The whitelisting was hidden by the last release. You can whitelist by setting the desired blocking mode for the URL specifically. If you want to whitelist an URL just give it an "allow everything". You can still whitelist a site from the notifications. I should definitely clarify the description...
Adding an URL specific block mode:
go to options, click on the triangle next to the blocking mode, enter the domain you want to whitelist, click on the plus, now you can set the blocking mode for the domain.
PS: you can still enter something in the white list by checking expert mode, open the export settings page and entering something in the whitelist field.
EDIT: Is the screenshot of the settings not explanatory enough?
EDIT2: It's easier for us to communicate on github. If you have any questions - just open an issue. Here the communication is slow and not relyable.
EDIT3: please try version 0.4.4 - there the whitelist is available again. - 5점 만점에 1점Registrierter Benutzer 님, 8년 전reverted to 0.4.2 as 0.4.3 (all) is blocking pages, either when firefox starting with last session, or login to AMO

8년 전에 게시됨Can you please file an issue at https://github.com/kkapsner/CanvasBlocker/issues with more details. I already know that there are problem but I'm not able to spot them because I never had a reproduction scenario.
EDIT: Have you tried any of the Beta versions? https://github.com/kkapsner/CanvasBlocker/releases/
EDIT: Please try version 0.4.4 - 5점 만점에 5점Firefox 사용자 13600531 님, 8년 전This is a fantastic add-on for users who are concerned about privacy while surfing the web because it efficiently detects and blocks/fakes canvas fingerprinting. I use CB on all my machines with Firefox (52-ESR and >57) and it supplements nicely other privacy-related add-ons. Based on my own experience, I can also confirm that it receives superb support by a very helpful and responsive developer. Clearly a must-have five-star addon!
