Indispensable extension for anyone who seeks for privacy. Bad reviews are generally old, and the extension has improved over time.

I suggest warning users that they have some APIs that are disabled (by the user in about:config). This can render CanvasBlocker “weaker”, although this is not fundamentally an issue with it.

Like if you have `dom.webaudio.enabled` disabled in about:config. This can make you more unique and thus “fingerprintable”.

addons indispensabile per l'unicità e la protezione del fingerprint, ottime le opzioni di configurazione

A must have for anyone who cares about their internet privacy

Among the 30+ installed extensions, this is the only one that made me register a Mozilla account and give it 5 stars.

As far as i know it worked fine for me so far, but i started using Google Sheets and it kill the performance. Very laggy and slow sheets.
When i disabled this extension it started to scroll smooth as a kitty.

Update: disabling the extension on the site fixed the issue.

Recently i got trouble login in google when this plugin on. i use this plugin to set fake all fingerprint and google say that my browser is not supported when i try to login in using my google account.

I've been using this extension for quite a long while and it was working fine, but recently it has created trouble with ebay.co.uk on my laptop. I cannot navigate on eBay. I got the following error message: CanvasBlocker is slowing down Firefox. To speed up your browser stop that extension.

Плохо, что нельзя установить на Firefox для Android. А в остальном отличное дополнение!

Use it since years! Its GREAT if you want to set the User Agent globaly, which is required if you are using Multi Acc. Containers/Temporary Containers, because a fresh Container has the true User Agent no matter which User Agent Managing Addon I tried. This Addon also is one of the fews that has ALL APIs except the Font Fake Readout, slimming your JS Fingerprinting Addons down. Another major for me is that you can devicde if you want a fixed readout fake or like the DOM In and out be faked, because many addons do not let the user decide. Overall I hope it will be a long supported app, and would consider to donate without hesitation (Dev, please add some "civilian" payment method, because I will not send you BTCs :D sorry). And thank you again Dev, your work really is appreciated and I wished I could have helped you with the translation, but we speak the same native language so you have already done it ;o)
