In fact they are not "features".They are some information(audio channel count/rate/frequency, supported font list, etc) the browser exposed to JavaScript.
And websites can generate a RELATIVELY unique fingerprint using these information.
Their purpose is precision advertising, not tracking.
The fingerprint can identify the same computer on different sites, but they don't know who you are.
