screen of videos keeps pausing if played in background / different tab

When playing a video in background / different tab, the picture (screen) freezes after a few seconds, while sound still going on. It can be resolved by moving over the video picture with mouse cursor again, but it is nagging... Any idea what causes this? I noticed it in Youtube, but also Facebook videos...

It's possible that Firefox is throttling the connection of background tabs. This is usually done to improve performance, since (typically) tabs that are not active aren't visible to the user.

You can try setting the network.http.throttle.version preference on the about:config to 1 and then restarting Firefox. If that doesn't help, setting the network.http.throttle.enable preference to false and restarting Firefox may help.

Hope this fixes the issue for you.
