Ask HN: Does uBlock Origin block pixels?

"Pixels (aka web beacons/web bugs/java script). Pixels are tiny graphics with a unique identifier that are used to track the online movements of web users. Unlike cookies, which are stored on a computer’s hard drive, pixels are small graphics that are about the size of the period at the end of the sentence that are embedded invisibly on web pages or in HTML-based emails. Our third-party analytics providers may place pixels on the Site that track what other websites you visit (both before and after visiting the Site). Our third-party analytics providers use information obtained from pixels to help us improve our business and the Site. We do not control the use of pixels by third parties.
