Firefox Community Forum

Recently, I've been noticing an issue with Firefox's built in Picture-in-Picture (PiP) feature. When watching media, such as a YouTube video, using PiP, the video runs as normal, but recently, the PiP completely breaks when I tab away from my Firefox window to do something in a different app. This wasn't the case a few months ago, so I'm not sure what changed to make this error happen. I had attempted to disable hardware acceleration to see if that was the issue, and nothing changes when it's enabled versus when it's disabled.

We are unable to stop playback from the controls in the PIP window for Apple TV when the video playback was started in the main browser window. If we press the control the playbacks stops for a fraction of a second and continues again. Other controls like mute etc. are working as exspected.

If we start the playback in the PIP window we are able to stop it!

If we use Youtube or Amazon as a video source the problem does not show.

If we use Troubleshoot Mode we get exactly the same behaviour.

Any Ideas?

When a video is popped out, in PiP mode, and the "owning" page is scrolled such that the video "origin" scrolls off the viewport, the PiP video pauses. If the video is started again, and the page is scrolled more, it will re-pause.

This seems to be a Firefox behaviour and not a site-specific one.

Is there a setting to keep the video to continue playing?

This would be helpful on Twitter/X, for example, when scrolling the timeline with a PiP playing from a tweet.
