@Andreas_Hegenberg When playing a youtube vid. in Show Floating WebView (html inserted). After closing the webview window (by cmd-w or red dot upper left corner). The youtube audio keeps playing. Is this expected behaviour?

If you are using the old "Show Floating WebView/HTML Menu" action, you can activate this option:

have this already checked

I think you are right, there was a potential retain cycles (i.e. the webview not really being closed) with some configurations. Could you check whether 5.489 solves this for you? (uploading now)

red dot upper left corner closes the window and audio, cmd-w closes the window but not the audio
