I've found that the buttons do not work for all. Digging a little deeper finds there are several issues that cause the videos to play anyway: http://www.ghacks.net/2015/06/11/finally-mozilla-adds-working-html5-video-autoplay-blocking-to-firefox/ and this: https://bugzilla.mozilla.org/show_bug.cgi?id=659285 "Bug 659285 - Extend media.autoplay.enabled to provide a way to disable untrusted play() invocations" I tested autoplay blocking with the following prefbar button in Firefox 42 (dev) and autoplay on/off is working there. So it's fixed in Firefox 41/42, but now the trick will be to get it fixed in SeaMonkey (2.35 and other versions). autoplay.btn { "prefbar:info": { "formatversion": 3 }, "prefbar:menu:enabled": { "items": [ "prefbar:button:autoplay" ] }, "prefbar:button:autoplay": { "type": "check", "label": "AutoPlay", "prefstring": "media.autoplay.enabled", "topref": "value", "frompref": "value" } } _______________________________________________ support-seamonkey mailing list [email protected] https://lists.mozilla.org/listinfo/support-seamonkey
