How do I stop Firefox allowing websites to control other tabs open to other websites?
When Instagram plays a video and I move to another tab (other than wherein instagram.com is open) then suddenly the Instagram video stops playing completely.
How on earth is this possible in "privacy first" Firefox? When did I gave permission for a video to stop playing just by clicking another tab?
I want a standard HTML5 video to continue to play in any of the tabs that are open regardless of which tab I am clicking-on in the middle of play. Once upon a time that was the case. I want to go back to that state please.
