Firefox@Lemmy.world: Does Firefox block websites from uploading data that could be used for fingerprinting like resolution, installed fonts, etc.?

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.
