- by Firefox user 15054524, 2 years agoRated 5 out of 5Excellent add-on, works as advertised. I would appreciate author's opinion on how this add-on interacts with Firefox's new built in fingerprinting protection as of version 67, and whether this add on provides additional protection.
Thanks for everything!!Developer response
posted 2 years agoThe interaction with Firefox's new protection is discussed here: https://github.com/kkapsner/CanvasBlocker/issues/349
In short: the new feature from Mozilla is good but CB still offers additional value. - by BigDargon, 2 years agoRated 5 out of 5
- by Firefox user 15038450, 2 years agoRated 4 out of 5I 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.Developer response
posted 2 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. - by Firefox user 15030259, 2 years agoRated 1 out of 5I'll gladly change my rating if this is shown to be user error but I disabled every other add-on in Firefox except CanvasBlocker, went to browserleaks.com/canvas and ran the test, and the Fingerprint "Signature" field always stays the same no matter what. If I uninstall CanvasBlocker, it's the EXACT same signature as when the extension is installed. I have used the default settings and I have also tried tweaking the settings. The signature NEVER changes.

posted 2 years agoI do not think this is a user error. But with the given information I do not know what's the root cause of the problem. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with detailed information (e.g. used browser version and operating system) so I can reproduce the problem. - by Firefox user 13044013, 2 years agoRated 5 out of 5

- by ZeroAnarchy, 2 years agoRated 5 out of 5Свою задачу выполняет, в редких случаях ломает сайты и приходиться временно выключать защиту.

posted 2 years agoIf CB breaks a page you can whitelist the page (temporarily) so you do not have to deactivate it completely. - by active x, 2 years agoRated 5 out of 5This is an excellent extension, and I recommend it to EVERYONE. Thank you, so much, kind developer <3

- by Firefox user 14090498, 2 years agoRated 1 out of 5I tested with https://browserleaks.com/canvas and even when the "Signature" changes everytime I reload the test the "Unique Fingerprints" at "Database Summary" is always the same. Why? is this a way they can still track me??? I might improve the rate after clarifying. Thanks
Developer response
posted 2 years agoActually I'm not sure what the section "Database Summary" is all about and whte the "Unique Fingerprints" really count. Maybe they only include fingerprints in their database when they see it more than once (or the count is not live but only updated in some time periods).
As the signature changes every time CanvasBlocker is working as intended. This is the tracking information CanvasBlocker protects.
Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss the impact of that (communication is way better there). - by Firefox user 14787168, 2 years agoRated 5 out of 5
