How to disable system fonts to stop browser fingerprinting in chromium

I used https://panopticlick.eff.org/ to scan my browser for fingerprint uniqueness and was shocked to find my pretty unique system fonts (I use from windows because I like them) being  18 bits of identifying information. I googled for it but can't find how to hide this info. Do anyone know?

I don't think Google is in the business of making a privacy oriented browser

Don't allow webpages to run random scripts.

In FF go to about:config and change "privacy.resistFingerprinting;true"

Should that not raise your ID?

Edit: speaking of which and reg. mitigation: fake the useragent to say windows …
Edit #2: … or android

It looks like the results are different than the last time, it is a loosing battle

Edit: as far as i know linux font rendering in html5 canvas automatically makes you fingerprintable

Re: How to disable system fonts to stop browser fingerprinting in chromium

I am getting better results with tor browser + ublock origin, in full screen. 15.56 bits of identifying information.
Tor browser uses common user-agent and fonts ( not system-fonts) so it helps.
