Does not make my canvas fingerprint less unique according to panopticlick. I'm still 1 in 1.9M, which is pretty bloody unique.

Yes, I've closed and reopened the tab, I've done Shift+F5 (which opens the devtools?) and everything. The result stays the same: this addon doesn't appear to do anything.

Very useful for privacy

Doesn't make my canvas fingerprint less unique. amiunique.org still tells me that my similarity ratio is below 0.1% which means I have a very unique canvas fingerprint.

Canvas Fingerprint Defender has a bug on chrome, i tested it also on firefox has this bug.
Canvas Fingerprint Defender will cause website auto jump failure.
you can reproduce in this link:

no matter login or register, page does not auto jump.
Maybe make a option to keep a same Canvas Fingerprint for a while like 5 minutes would solve it.

I love this Firefox addon, the reason I gave 3 stars its because it will always show your fringerprint in the first session, if you refresh, them it will change it, but the first one, it will always show your real one.
But, well done! I am considering donating to see if they can fix this issue.

please
add an option to not send a notification each time

Had to close the https://browserleaks.com/canvas site and open again (reloading was not enough) to see a change, but now it works.

good use

It's not working. Tested on https://browserleaks.com/canvas my fingerprint remain the same as without this extension.
Still not working. Maybe a conflict with an other addon privacy/security oriented. I don't want to disable them so I found another solution working for me. Thank you.
