Another example:
https://olhardigital.com.br/coronavirus/video/por-que-o-sequenciamento-do-genoma-de-virus-e-importante/97743

I can see video but can't lauch PiP.

If I extract the URL from iframe and open in a new tab, I can use PiP #DailyMotion:
https://www.dailymotion.com/embed/video/x7sjebv?api=postMessage&apiKey=37107c4d6bdc636d7689&autoplay=false&endscreen-enable=false&id=player_dailymotion&mute=false&origin=https%3A%2F%2Folhardigital.com.br&sharing-enable=false

Thanks!

This is working for me (Linux, d2ac41047c10 2020-03-07), but that's calling itself 75.0, so I'll get a more recent build and see if I can reproduce then.

Okay, I've tried this with 76.0a1 (2020-03-14) (64-bit) Linux WebRender, and the PiP stuff works fine for me on the Olhar Digital page.

Wellington, can you visit about:support, click "Copy text to clipboard", and paste that into this bug?

Also, can you try reproducing the problem with a fresh profile? Run Firefox passing the -ProfileManager flag, and it should be clear how to create a new profile. https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Multiple_profiles#Profile_management

Looking at the about:support, it looks like Fission is enabled. Picture-in-Picture currently doesn't work correctly on some sites when Fission is enabled. That work is being tracked in bug 1575868.
