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.

- Rated 1 out of 5by CHANO, 6 days agoI became suspicious when there is no tally count, so I went to coveryourtracks.eff. ran the fingerprinting scan and found the app was doing absolutely nothing at all but sitting in my browser collecting info.I will be removing it.And running a system malware scan.

- Rated 1 out of 5by NameOfDisplay, a month agoI 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. - Rated 4 out of 5by Mikaela, a month ago

- Rated 3 out of 5by Firefox user 19062474, a month agoNo instructions on how to use it. Not intuitive to use. I have not a clue if it is doing anything because of this. I will leave it on incase it is working. It would be better as an app to work all the time my device is on rather than just inside my browser.

- Rated 4 out of 5by Firefox user 12814982, 2 months agoAn sich ein wirklich klasse AddOn, was Webseiten definitiv zu schaffen macht.
Leider bremmst es den Browser je nach Seite extrem aus.
Gerade Karten-Webseiten wie z.B. Google Maps sind teilweise unbenutzbar, wenn der CanvasBlocker zuschlägt.
Der Blocker von Firefox selbst, ist hier etwas harmloser, dafür aber auch von der Block-Qualität schlechter. - Rated 5 out of 5by Rinshun, 2 months ago

- Rated 5 out of 5by Firefox user 17288647, 3 months agoThis is a game changer. This security add-on compliments your VPN and enhances the security of your web surfing experience. You should include this as one part of your layered strategy security plan.

- Rated 5 out of 5by t3 ur u4 to c3, 3 months agoits good but it would be great if right-clicking on the extension also had an option to temporarily disable it for testing purposes

- Rated 4 out of 5by B00T987, 3 months agoI love this extension! However its a bit hard to use, because you have to uninstall, and reinstall the extension to open up the easy to use settings picker. If you change your settings as often as I do, if not then this is an easy 5/5 extension.

- Rated 4 out of 5by AnoniM0US3, 3 months agothe addon prevents "youtube comment search" addon from working
is there a way to fix this, without having to turn canvasblocker off each time?
or even better: can i block or unblock each element separately, until i find the culprit? (the way "NoScript" addon visualized this is very beginner userfriendly)
thank you - Rated 5 out of 5by Firefox user 18369793, 3 months ago
