FluentPlayer controls not appearing or responding after starting play.

Hi. I have tried embedding a Vimeo link into FluentPlayer, both on a webpage and in a post in FluentCommunity, when the page is displayed in the Firefox browser, after play is selected, the controls for the video do not reappear when the mouse hovers over the video or when it clicks on the video.

Is anyone else have issues embedding a Vimeo link into FluentPlayer displayed in the Firefox browser?
