It also adds to the users experience in Google search results. Video results will display visual summaries and related videos will appear on the page. VideoSurf pulls videos from a variety of video sources.With all of the addons video displays, you can hover over the videos and they will begin to play, allowing for a similar preview experience to what Bing offers in its video search you know the one that got people talking about watching porn at work when Bing first launched. With the addon installed, you also get some extra stuff when you visit YouTube, including results from other video sources beyond YouTube.
