Prevents YouTube and Vimeo from pausing videos when minimizing or switching tabs. Cross-browser port of https://addons.mozilla.org/en-US/firefox/addon/video-background-play-fix/
< Feedback on Video Background Play Fix
I don't know how long you have to wait to get that, but I just updated to the latest extension code if you want to try it.
Before it was possible to keep using the mobile yt website, and minimize the browser, and the video kept playing.
But not when the yt mobile website is used and the browser in not on focus the video stops playing.
Your script also does not prevent YT from auto pausing the video and asking "are you there?/keep playing".
After your last update, as you could see, a lot of people complained that it totally stopped working on any chromium based browsers, including the Kiwi Browser, so please update your script soon, as long as you take to do so, as more users your script loses.
It had support to disable the "are you there keep playing" boxes, but now the script doesn't stop them so the video keeps stopping.
