PreGBox is a Chrome extension that allows previewing videos from Google search. It adds a small button next to videos that appear within the search result which enables previewing the video without having to leave the search page or opening it in a new window or tab. Videos within the search result are supported from YouTube , Vimeo, Yahoo videos , DailyMotion , Tagtelt, etc.
After PreGBox is installed in Chrome, it automatically adds a button next to the video. Clicking on this button provides a video preview within the Google search page.
This makes it easy to preview videos before opening them, in order to find the most appropriate video. Moreover, the video preview is so smooth that one can easily watch the video within the search result without requiring to go to the original video page. Using PreGBox, you can also avoid running into spam videos as a preview of the video can be seen before opening it separately. Having said that, it is unlikely that you will be wiling to view the video separately, as the preview box is quite convenient.
You can grab this handy extension from the Chrome web store link given below.
