I want firefox browser to stay persistant on top of all other applications, with its open tabs. this way I can swap between youtube videos as its always on top, I like to layer my music (jazz, whitenoise and fireplace) and swap between the videos and have them playing in a small window at corner of my screen. (just one tab visible at a time). but the firefox browser always on top other applications just like windows clock/timer can do.
also if can have pop out window of the youtube video like Edge, where the window of the YT video has no borders and stays floating above all other applications, like windows clock or timer. and you can resize that window to place it anywhere on your screen, its a nice little entertainment device for video music or scenic video as I work.
Thank you,
