Fingerprinting works by collecting bits of information about the browser and device to identify users. Couldn’t browsers like Firefox see when a website gets such info with JS and either prevent or ask permission from the user for the website to make HTTP requests to upload such information to the website. Idk if they do something like this already.

Even if you would be able to track js code like that, the js code can react to it’s own sideeffects. E.g. have 8 Elements and encode the 8-bit Fingerprint as a custom style sheet that adds an animation some of the 8 elements. Then react on the animation events and rebuild the fingerprint. It’s virtually impossible imo. Maybe it can even be formal proven.
