User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 Steps to reproduce: visit any web page with an audio element with controls, e.g. http://output.jsbin.com/hocuha or https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all Actual results: There is a ridiculous tooltip which moves along with the current position cursor on the seekbar, with the current time on it. It's very annoying to have to follow it as it moves in order to read the time. Additinally this creates all sort of layout issues: the floating tooltip could partially cover other stuff (e.g. text that you're trying to read) above the audio player, or on the contrary, by covered by it as in bug 1344569 And if the audio element is at the top of the page, the tooltip even gets cut by the top of the window: http://output.jsbin.com/jamubop which is demential. Not only it's a bad idea in the first place, but the trivial cases where it breaks weren't even considered and dealt with properly. Expected results: the current playing time (e.g. "00:30") should be shown in a fixed place, on the left or right of the seek bar, just like in decent browser (e.g. Chrome). It should be next to the total time, in the format current_time/total_time, e.g. "00:30 / 07:45" I attach a sketch just to clarify what I mean

This will be fixed in Firefox 53.
