The PopVideo add-on for Firefox allows you to view YouTube videos or video sharing sites in a pop-up window in the browser. Using the add-on is very easy – after installing the add-on in Firefox, when you watch any video, simply move the mouse to the upper right side of the video, an icon will appear, click on it and the video will be displayed in a pop-up window, allowing you to watch it without staying on the same window, thus enabling you to watch while browsing.

You can watch videos from sites like YouTube, Dailymotion, Vimeo, Youku.com, Tudou, and others, and even videos from other sites. Once the add-on recognizes the video on the page, it will show an icon to view it in a pop-up window. This add-on is very useful as it saves you time and allows you to watch while browsing easily.
