And I can't use PiP in that site. :-(

Thanks!

And I can't right click because there is a 'div' over the video element.
Only if I inspect the page and delete the 'div' I cant right click and enable PiP.

Make PiP button available over 'protection div's'.

Thanks!

Hi,

Thank you for the report. I was able to reproduce the "InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable (PictureInPictureChild.jsm:114)" error on Windows 10 x64, Mac 10.14 Ubuntu 18.04.3 LTS with Firefox versions Beta 73.0b11 and Nightly 74.0a1 (2020-01-31) following the bellow steps:

1. Open https://www.pscp.tv/w/1djGXQewoBeJZ.
2. Click on the "Play" grey round button.
3. Reload the page from step 1.

Notes:
on Windows 10 x64, Mac 10.14 and Ubuntu 18.04.3 LTS with Firefox version Release 72.0.2 the "InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable (PictureInPictureChild.jsm:92)" error was displayed in the Browser Console when following the steps described above.

I am not sure about the component, if the selected one is not right, please feel free to change it.

I can also reproduce this by accessing games from y8.com sites and other random browsing on Windows 7.
