- Оценено на 4 из 5от Jezze, 8 лет назадDoesn'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.
Ответ разработчика
размещено 8 лет назадIn 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 - Оценено на 5 из 5от Пользователь Firefox 13835690, 8 лет назадThank 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.

размещено 8 лет назадPlease provide a reason why you gave one star. Maybe I can fix the issue or improve CB with your input. - Оценено на 3 из 5от Пользователь Firefox 14072583, 8 лет назадDoes not work according to fingerprint test at https://panopticlick.eff.org/

размещено 8 лет назадWhat 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. - Оценено на 5 из 5от ©®°˜, 8 лет назад100% 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 easyОтвет разработчика
размещено 8 лет назадPlease 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. - Оценено на 5 из 5от Пользователь Firefox 14039775, 8 лет назад

- Оценено на 5 из 5от Gummi, 8 лет назадCan't seem to get version 0.4.4b working with Firefox ESR 52.7.2, there's just no icon visible anywhere on the UI.
Edit: My bad! I remember that this addon had an icon before but nowadays it hasn't. Works great!Ответ разработчика
размещено 8 лет назадThis 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. - Оценено на 5 из 5от Пользователь Firefox 13870378, 8 лет назад

Ответ разработчика
размещено 8 лет назадYes, 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. - Оценено на 5 из 5от Salsa, 8 лет назад

since update from 17dec, blocks all web-pages :(Ответ разработчика
размещено 8 лет назадI 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 - Оценено на 2 из 5от Fred Thompson, 8 лет назадDescription claims there is a whitelist option but...there is no visible way to see, let alone edit, such a list.
Ответ разработчика
размещено 8 лет назадThe 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.
