This extension works on top of the Google search results page. The basic idea is to eliminate the "extra" hop between clicking on a Google Search result item and loading the desired page. When you are not using this extension, you will see on the monitor tab (developer tools) that Google sends you to a "google.com/url?" page and then to the website you requested. Behind the scenes, there are two positive side effects: more privacy (avoiding a tracker, google.com/url) and a faster browsing experience (fewer requests to load a page). The first image has a blue line on the network monitor (bottom); this is the additional request to google.com/url. Plug-in is enabled on the second image, so there is no further request between clicking on the result link and loading the page.
