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 easy

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.

- This add-on breaks Google Maps on mobile. Google Maps is completely unusable; I am forever stuck on a constantly loading page that keeps switching between a blank page and the Google Maps page. Uninstalling this add-on did nothing, clearing cache and cookies did nothing, and even whitelisting the site itself in Canvas Blocker didn't do anything. I only ever started having this issue upon using this add-on.
And no, I'm not making an off-site account just to report this problem, I'm posting it here. Ridiculous. - 评分 5 / 5来自 Firefox 用户 19544944， 2 个月前

- One of the essential plugins for everyone that care about anonymity when you surf on the web. If you stay on one of the 2 lowest settings you can increase your anonymity dramatically on the web without breaking functionality, so you can surf the web pretty much like everyone else without even noticing it while still staying hard to identify if you for example combine this with VPN. This alone will help but its one of several other key plugins you should install to shield yourself against tracking on the web.

It blocks or fakes the data that websites use to track your device without your consent. I like that you can customize how strict it is for each site, so if something breaks, it’s easy to adjust. It runs quietly in the background and doesn’t slow things down. A must-have for anyone who cares about online privacy and wants more control over what sites can learn about their system.

- 评分 5 / 5来自 Edgar Almeida， 4 个月前Seems to work, if you test it at browserleaks(dot)com / canvas with the plugin on, keeps giving new signatures at each refresh, if you turn the plugin off, the signature will remain the same
- Works very well. If you want to test this addon whether it works or not, just visit the page which is mentioned in the description. (for example: browserleaks website)
It's just a shame that I only recently discovered canvas fingerprinting, even though it's been around for so long. Keep your privacy up folks. - 评分 5 / 5来自 Firefox 用户 19145735， 6 个月前
- 评分 1 / 5来自 NameOfDisplay， 7 个月前I like the concept of the addon but this is basically useless until the developer explains literally anywhere how to add sites to the whitelist and the settings page doesn't absolutely suck.
Only really useful if you are the developer and understand all of the obtuse menu options.
