Rated 4 out of 5
by Firefox user 15038450, 6 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 6 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 5 out of 5by tutzlima, 5 days agoI use this extension together with "AmIUnique" and, based on this, i have no complaints. There were few moments that my fingerprint was collected by AmIUnique, but the *most* were specific moments that I turned off the canvasblocker for testing.

- Rated 2 out of 5by blackSP, 2 months agoChecked before and after installing/activating this extension trying all profiles and see zero improvement in my identification score on several fingerprinting sites like coveryourtracks.eff.org and amiunique.org. Benefit of the doubt after reading dev's comment that it works anyway. Can't find any proof of that though.

posted a month agoYou need to check the details of the fingerprinting sites. Depending on your settings you can have a unique fingerprint - but this is not a bad thing if it changes: https://canvasblocker.kkapsner.de/faq/#uniqueFingerprint - Rated 5 out of 5by Firefox user 17902463, 2 months ago

posted 2 months agoUnfortunately the workers do not offer an API to interact with them from a web extension. That's why I opened https://bugzilla.mozilla.org/show_bug.cgi?id=1636977.
So I do not see a maintainable way to handle this issue. (The only would be to disable workers...) - Rated 5 out of 5by Firefox user 18605300, 5 months ago
