Canvas Fingerprinting – BrowserLeaks

I am not sure what it measures, but my privacy enhanced Firefox for browsing seems to show random numbers every time I load this URL and I always stay "unique". Another browser shows "signature stats". If I use my firefox, this won't even show.
My Privacy Plug ins:

You can test your browser here: https://coveryourtracks.eff.org/ Brave works super well for me. Chrome not so much.

Currently use Safari and there's no protection against canvas fingerprinting :(

This is a pain point when making browser games, as custom fonts break way too easily in some environments.

My Brave browser seems to be 100% unique.

It should give a fingerprint. Try to reload in another tab and see if you stay unique and if the fingerprint changes. I am also unique, but I always stay unique ;-)

Apple once disabled canvas for their devices for this reason and broke all my apps, haha.
80% of my projects use canvas
PaleMoon browser has a canvas.poisondata config setting (also available in the Preferences GUI) which prevents such fingerprinting. However, note that these things are not used in isolation - browser fingerprinting is done by collecting various other data too, and when collated together, these can provide enough uniqueness to identify (or categorise) your browser into some specific group. We are fighting a losing battle for privacy.
