Current firefox incognito mode seems to defeat the fingerprinting.

Thanks for letting me know.

Firefox seems to have added noise to canvas and webGL output when in private browsing as of v120: https://www.mozilla.org/en-US/firefox/120.0/releasenotes/

Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy.

Additionally, there are inconsistencies between notification permissions in private windows.

Thank you for pushing the envelope and sharing!!

Noise in the canvas, well that's an interesting defense.

I noticed detectincognito is also affected: https://github.com/Joe12387/detectIncognito/issues/36
