You already know about cookies, but did you know you can be identified by the fonts that are on your computer? Firefox is a good choice, and when version 52 arrives later this year that protection will get even better. Firefox 52 will help prevent sites from tracking you by checking the typefaces that you have installed on your computer. Can you actually be identified by the fonts on your computer? When a site requests a list of the fonts on your machine, Firefox 52 will only return those approved fonts.
