By now the Panopticlick test has lost its validity. The AmIUnique test remains fairly valid: https://www.amiunique.org/ Here is my test Amiunique.org script allowed: As you can see I pass some tests with the result is poor, the background in the percentage is red. And although there is no "unique" value the website claims that I am tracked. I feel sorry for them, but: My browser is New Moon and I'm with Windows XP, I have 1 plugin, and I have Flash installed:

CanvasBlocker v1.4 Released (November 9, 2020) https://addons.mozilla.org/firefox/addon/canvasblocker/
Sorry to bother you but I have a question. Are you still using Trace? The reason for asking: I used the free version for a while before upgrading to Trace Premium in April 2019. It still works including the premium blocklists and premium features with Vivaldi, Brave and Firefox browsers. (I use the same license for each browser). I've never been asked to renew my subscription so I wonder how long the license is valid for.
Hi @Callender , I have the free version only in Brave and Chromium Edge. Can't help you with licensing issues, sorry.
Considering the features Brave has gotten over time, I have my doubt Trace would be useful in it now.
@Krusty @Azure Phoenix I don't use Brave. Can you post some tests (BrowserLeaks) to verify? P.S. I have a lot of free time. My region (Tuscany) in Italy is red, so we are in lockdown and I don't work.

@Azure Phoenix Thanks. It is identical to the one I implemented in my daughter's PC W.10 that uses Chrome. Except that the values you wrote that in Brave change when the browser is restarted, in Chrome they are obtained when the web page is reloaded.
Well here's mine (Panopticlick). Each visit some values change therefore not trackable. A unique fingerprint each visit but that fingerprint changes each time. Then BrowserLeaks - two consecutive visits without clearing any browser data. What I find most interesting: If visiting certain file sharing websites - on some you can only download one file then if you try to download another you get a message stating that you just downloaded a file and must wait x number of hours/ minutes or days before you can download another. However with proxy ip header spoofing enabled you just close the tab, open a new tab and visit the site again to download - no problem.
https://fingerprintjs.com/ is a good test, but all these tests have relatively limited value. Brave is probably best used in its vanilla configuration using its built-in features and not a load of extensions. If a user wants anonymity then Tor is a must, along with other measures.
Interesting test: https://webbrowsertools.com/canvas-fingerprint/ Not like the stupid test (EFF) recently appeared in gHacks. My result with New Moon 28 in Windows XP: No dedicated extension. I remind the members of W. that the blocking of javascripts prevents the detection of many fingerprinting techniques, including the Canvas.
CanvasBlocker v1.5 Released (January 18, 2021) https://addons.mozilla.org/firefox/addon/canvasblocker/ Spoiler: Changes v1.5 new features: - added {empty}, {false} and {undefined} to webGL preference parameters (i.e. VENDOR, RENDERER, UNMASKED_VENDOR_WEBGL and UNMASKED_RENDERER_WEBGL) - added {disabled} to UNMASKED_VENDOR_WEBGL and UNMASKED_RENDERER_WEBGL to disabled the WEBGL_debug_renderer_info extension - improved performance for protected canvas part "input" fixes: - protection of DOM manipulations on unloaded windows may break websites known issues: - if a data URL is blocked the page action button does not appear
Probably another way is to use Firefox hardened or Icecat Weasel with the Multi-Account Containers and Cookie Autodelete addons (whitelist only for logins). Put social network accounts in separate containers, and use fake Google accounts in any of them if needed to access Youtube videos, etc. Run any personal or business Google account in another browser, like Iridium.
I agree with Sven Taylor of the unnecessary presence of Cookie Autodelete: https://restoreprivacy.com/firefox-privacy/

I tried after a long time to do the BrowserLeaks Canvas Fingeprinting Test with my Edge without any particular dedicated extension. My score is 100% https://browserleaks.com/canvas
I don't know about fingerprinting specifically but Edge seems to have improved its Tracking Protection significantly, though I can't find any current documentation to support this.
