Apple added a Picture-in-Picture (PiP) to Safari a while back. It’s a fantastic feature that places videos from web pages in a separate window that floats over all other windows. The problem is that Apple’s implementation doesn’t work unless the website has implemented it on their end… which most sites haven’t done.
PiPTool to the rescue! This nifty little Safari extensions adds PiP functionality to ANY video on ANY site. All you have to do is go to a page with a video you want to watch, click the PiPTool button in Safari’s toolbar and click on the video you want to be PiP’d. You can resize the window and move it from the top right corner by holding the Command key down while dragging the window.
I’ve been using PiPTool for several weeks and haven’t come across a single site it doesn’t work with.
