Always gives a unique and new fingerprint. Tested with browserleaks.com
Everytime you reload, you are someone else :)

works really well.
i do wish that all the different fingerprint defender addons were just one addon, where you could turn on or off the different protections.
i would also love to be able to temporarily turn off fingerprint hiding from within the addon menu (rather than having to go to about:addons).
would also love to be able to whitelist sites i trust. (see ublock origin which does all of the above very well)

It is a very good and useful add-on to protect yourself in this online wave where many websites and servers try to exploit user data without appropriate discussion, espeically when for younger generations where the awareness of online security and true freedom is becoming more vital than ever before.

Works as intended when testing with fingerprint testers although https://coveryourtracks.eff.org shows that canvas fingerprint is randomized witch by itself is fingerprint so might be kinda useless in this state if website uses good enough fingerprints

The idea is good but does not work I made 3 connections with screenshot to confirm. With VPN │Without VPN │Incognito
My fingerprint always remains the same and the technical demo knows if I am in private mode. I invite you tried.

I'll contact the developer to see what he thinks!

This addon seems to work as advertised. I do wonder about one thing, which is that the pop-up that notifies me when fingerprinting attempt is happening, also has an "Activate" button on it, which is confusing because, according to the author, once installed it is active. I have clicked on the "Activate" button several times and each time it pops up the button is still there. It makes little sense to me. But aside from that, it's good. I recently tested it on Browserleaks.com and it changed the fingerprint each time I refreshed.

Passed the Panoptick test with all the other defender addons from ilGur the author of this addon. So it works, I only request maybe consolidate all the "Defender" addons into just one instead of 4 separate ones.

very good,
has any of you compaired this extention to “Fingerprint Shield” ?

This is an out-of-the-box working solution, no strange and alchemic configuration needed. Works as expected.

Some sites stop working well, i would apreciate a whitelist option.

Works great, was using CanvasBlocker and noticed it impacting performance, testing with speed-battle.com CanvasBlocker was reducing my Render from around 150 to 20. I removed and tried this plugin and my Render went UP! Plus on browserleaks it worked flawlessly and even gives little notifications.

Highly recommend, without even losing performance!

This add-on (and its siblings from the same developer) behaves nicely. It alerts you to fingerprinting attempts, appears to successful obfuscate your fingerprint, based on a number of testing sites I have tried. It asks for minimal permissions and you can toggle the alerts from the toolbar icon. The website it links to explains the functionality clearly.

The only thing missing is that it is not a Recommended Extension and/or endorsed by an objective organisation, ideally the Electronic Frontier Foundation (EFF).

I also wonder how necessary this is. Firefox claims to resist fingerprinting nowadays (https://blog.mozilla.org/firefox/how-to-block-fingerprinting-with-firefox/), but my assumption is that this is a more paranoid effort, which suits me. I would be interested to know more.
