Confirm closing YouTube

Add a confirm message when you attempt to close YouTube, optionally only when a video is playing

Do you accidentally close the browser window when listening to Youtube songs? Its a pain to go back to the exact moment of the Youtube video/song after you open the browser tab back up. This software solves the problem by having a confirmation window popup to confirm if you really want to close the browser if one of your browser tabs is on Youtube.com. Please note this software needs permission to run on all websites as the software needs to check whether your current website is Youtube.com. We do NOT check your browsing history/check your search data etc and the only purpose of having our script run on all websites is to check if you are currently on Youtube.com
