It can be a pain to find the right browser when you have a bunch of tabs open. Just glancing at the tab bar doesn’t help. That’s where those icons on your browser tabs come in handy. They are called favicons. In order to make things easier, YouTube will now display a “play” icon in its tab whenever a video is playing.
This allows users to figure out in one glance which is YouTube. Spotify and Soundcloud already do this. The “play” icon is displayed alongside the favicon and will definitely make it a lot easier to locate the tab.
It should come in very handy for those with many tabs open.
