    Seems to work quite well, was having an issue with cb and privacy badger would result in pages not loading at startup but latest alpha seems to have fixed that

    Do you have Privacy Badger installed? I can replicate your issue when both are installed (CB has to be activated first to reproduce it). But please open an issue at https://github.com/kkapsner/CanvasBlocker/issues to discuss your problem in details.

    I have only heard good things about CanvasBlocker! So i decided to try, and im sure its great, i just wish there would be a dummy guide for non tech savy people like me.

    I dont know why it works on some sites, and not on others? On YouTube its working directly and i can see many fake readouts, but on many sites it doesnt look like its active? The icon is green and i cant see any notifications about fake readouts.

    Having some sort of Q&A/wiki page is on my list. If you have specific questions you can always post them at https://github.com/kkapsner/CanvasBlocker/issues

    Some sites do not use fingerprinting. That's why the icon is green and no notifications show up. But keep in mind that not all notifications mean that a fingerprint is generated. Also legit use of the APIs can trigger the notification. It's just an indicator that CB did something.

    Edit: Now it's working again. I suspect the problem I had was caused by something else. Worked great up until July 10 2019. Then Gmail stopped loading, thumbs on Amazon, etc... After turning add ons on and off, this was the one causing problems.

    EDIT: great that it works again.

    Nothing was done to CanvasBlocke on that date. Last update was on the 6th. But on my end gmail and amazon work fine. Please open an issue on https://github.com/kkapsner/CanvasBlocker/issues with your details (used Browser version, CB version, CB settings, etc.). There we can communicate much better.

    Works great, tested both "block" and "fake" modes on https://www.deviceinfo.me. 5 star!

    Excellent 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!!

    The 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.

    Свою задачу выполняет, в редких случаях ломает сайты и приходиться временно выключать защиту.

    If CB breaks a page you can whitelist the page (temporarily) so you do not have to deactivate it completely.
