I remember a discussion with Kees1958 and the lead developer (and project leader) of JShelter over here and on Github, where Kees1958 even posted not to use JShelter because it randomized values outside the '"real world range". Later on the lead developer made a 180 and added an issue himself to randomize using a real world set or scope range. JShelter calls this little lies. The developers seem to be influenced by Brave a lot. I have not seen Kees1958 reconciling with JShelter.

From what I read and understand JShelter now seems to be the only free extension developing anti-fingerprininting which really works. I am using it on-demand (right click allow access to a website in Edge) using Chromium browsers option to use an extension on specific websites only. I also use a setting which is more focussed on little lies than protection (but still seems to work well, as posted in this thread: link to more farbling oriented settings)

It could just be me, but JShelter doesn't seem to prevent canvas fingerprinting for me anymore at browserleaks.com. It used to, but doesn't now. Can anyone confirm?

Update - Interestingly enough, JShelter works in a new profile. With my current one it seems JShelter is not working at all. But I can't understand why, and there's no indication.
Late response, it protects over different browsing sessions. When you refresh the page, the identifier remains the same, when you close and open the browser it is different. This is actually a good implementation, because it reduces website breakage (it is better your fingerprint remains the same in the one browsing session).

Since the Technical Demo gives me a new fingerprint after having closed and opened the browser canvasblocker seems to work ok. Thanks for the test site suggestion.

@Freki123 just go to Technical Demo - Fingerprint Pro and check whether your ID is unique between two browser sessions (after having closed and opened the browser) to see how effective CanvasBlocker is

@oldschool could you please try how FF with your hardened fingerprinting settings scores on Fingerprinting Pro?
Works with tweaked Firefox about:config settings without installing any extension. it says the ID will be the same even if connected to a VPN. Here on my tweaked config the fingerprint ID is randomized when I connect to a VPN + tweaked Firefox:

Without VPN + tweaked about:config settings:

--> No JShelter / Canvas Blocker required

Good to know, but I prefer
a) the AppContainer sandbox and other security enhancements of Edge over Firefox lagging security
b) Microsoft pre-loading Edge for (noticable) faster startup on my 10 year old PC
c) the option to use JShelter on-demand (no website breakage)

but in 2025 I will sitch to Linux and Firefox (when W10 eol), so thanks @Kongo for letting me know (y)

Good to know, I guess. I must have missed the part where you actually said what your tweaked firefox settings are. I assume it's at least privacy.resistFingerprinting=true.
