For those who find themselves wanting to pop a YouTube video out into its own window, this is the tool for you. Using the bookmarklet below, you can pop a YouTube video out into a resizable window so you can watch it while working on something else.
To use the bookmarklet, simply drag the “YouTube Pop-Up” link below to your browser bookmark toolbar (or save it anywhere in your bookmarks or favorites). Then go to a YouTube video page and click on the new bookmark. If all goes well a new window should appear with the video inside. Currently the bookmarklet only works on YouTube single video pages like this one, not other YouTube pages like channel pages.
The bookmarklet was originally written by me, Michael Wheeler, and has been substantially improved by others. If you find it helpful, let me know on Twitter or Google+. If you find a bug or have an improvement to suggest, please report it at the GitHub issue tracker.
