The introduction of a picture-in-picture option in web browsers has drastically changed the way we view video online. Instead of being tied to displaying images in a browser window or tab, P-in-P made it possible to view videos in a dedicated floating window that is always visible. Now Mozilla is taking P-in-P to the next level. The latest picture-in-picture update opens at least two video windows at the same time. The good news is that you can try this feature right now; Here is what you need to know. At the moment, the stable version of Firefox only allows you to run a single picture-in-picture window. In a move that breaks with what Firefox and other browsers currently offer, Mozilla is experimenting with giving users the option of running two or more P-in-P windows at any time. While the ability to run multiple videos frame by frame at the same time isn't everyone's cup of tea, it's still a useful option for anyone who wants to be able to easily switch between two or more videos without having to worry about multiple videos. browser tabs.
