By default, I have media.autoplay.enabled set to false. When there is a video I want to play, I use PrefBar to change it to true (selecting a checkbox on the PrefBar tool bar). I then reload the Web page, and the video plays. With media.autoplay.enabled set to false, I just now loaded a YouTube Web page with Bizet's L'Arlésienne Suites No. 1 & No. 2. There was no button to start the video. I then changed media.autoplay.enabled to true, but there still was no way to play the video. The video started after I reloaded the Web page; at that point, buttons did appear. -- David E.

No, I do NOT own a cattle ranch, a butcher shop, or any other business doing commerce in meat. _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
