Review by Firefox user 15038450
Rated 4 out of 5
by Firefox user 15038450, 5 years agoI changed my rating.
Originally I put 1 star because:
1. https://amiunique.org/ reports me as UNIQUE.
2. No support email, only github (I don't even know what it is and I do not want to create account only to ask for support).
Happy to change rating if I receive support (not github but email or phone) and problem is fixed.
----------------------------------
I changed to 4 stars because:
1. I was explained that it does not matter if I am unique as long as my profile changes each time which, apparently, it does.
2. The developer contacted me privately even though he's alone and he's not a company or a team. I appreciated that.
3. I put 4 stars instead of 5 because we have become used to better user interface layouts.
All in all I am happy and I recommend it.

posted 5 years agoThe same issue is discussed at https://addons.mozilla.org/de/firefox/addon/canvasblocker/reviews/1141570/ and https://github.com/kkapsner/CanvasBlocker/issues/154
In short: it fine to have these sites to report a unique fingerprint as long as the fingerprint changes (which is the case in the default CB settings). You can open up the console (Ctrl + Shift + K) and have a look at the actual fingerprint. There you will see that the protected fingerprints change with each reload.
Regarding support: github is mainly a code managing service (you can look at the complete source code and history of CB there). But it also offers a requirement and bug tracking feature. As I am only one person I have no time to give individual email (or even phone) support. On github some helping angels can support me. Also it provides an overview of already asked questions and open issues so other people with the same issue can see that it is known and/or what the solution is.

- Rated 4 out of 5by Leon Edwards, 4 days agoGood for anti fingerprint - but you need to rotate the fingerprint each * seconds and add Cloudflare captcha.
- Rated 2 out of 5by Firefox user 14059926, 7 days agoHas started to suddenly break a lot of websites, even while I have done no configuration changes in years. What's interesting that sites are broken even after disabling CanvasBlocker on a specific website (using the icon in the extension menu), only working once the entire extension is disabled. An example is a Grafana instance on the local network that I thought was a server-side issue, but was caused by CanvasBlocker (even while it was disabled for the domain).

- Rated 3 out of 5by Firefox user 18415085, 13 days agoI love this extension, but it is breaking Linkedin right now. There is an issue open on github already, are there plans to fix this issue in the upcoming weeks?

- Rated 5 out of 5by Nero, a month agoFunktioniert einwandfrei. Ist dass Add-On sinnvoll, wenn man privacy.resistFingerprint aktiv hat (about:config) ?

posted 25 days agoJa, es bietet weitere Funktionalitäten. Siehe https://github.com/arkenfox/user.js/issues/767 und https://github.com/kkapsner/CanvasBlocker/issues/158 - Rated 4 out of 5by Firefox user 18383988, a month agoOverall works well BUT, when protecting Navigator (choosing a different OS or browser, any of the 2) it is caught by https://iphey.com/
Developer response
posted a month agoNavigator protection is always tricky and you cannot hide it completely. But if I choose a different OS it does not get caught by this page. Maybe there is something additional that causes that in your setup. Developer response
posted a month agoPlease open an issue at https://github.com/kkapsner/CanvasBlocker/issues with your details. This should not happen and I do not see a massive memory consumption.- Rated 5 out of 5by Firefox user 18252931, 2 months ago

posted 2 months agoPlease revert to version 1.9 - version 1.10.1 is in the works.
See https://github.com/kkapsner/CanvasBlocker/issues/699 and https://github.com/kkapsner/CanvasBlocker/issues/700 for the progress of the solution.- Rated 5 out of 5by Tiger, 3 months ago
- Rated 3 out of 5by emotwink, 3 months agoThis particular extension draws too much power from my laptop. Otherwise it is working incredibly well.

- Rated 4 out of 5by snadge, 4 months agonot perfect, but it helps, especially if it is used with other addons, it still doesn't randomize your fingerprint like BRAVE does, only BRAVE gets 3 yes's on EFF's 'cover your tracks' (Ads, Trackers, Fingerprints), or, this addon, with Ublock Origin, Privacy Badger, Local CDN and NoScript (is what I use on Librewolf) gets you all 3 yes's on EFF (1 in 900, so 'common as muck' fingerprint, and unable to track & trace through fingerprinting)
