Existing addons (such as nobuffer and flashblock) seem to have stopped working; and youtube hasn't given users an option to prevent videos from buffering and playing automatically since they introduced this "feature". I've tried changing media.autoplay.enabled in about:config to false, but it had no effect (aside from breaking Pandora).
I want to stop both flash and html5 videos from autobuffering/playing.
Nobuffer used to accomplish that.
Flashblock used to block both flash and html5 video; but now YT videos seem to be encased in some sort of shell which prevents even flashblock from stopping autoplay/buffer.
I don't care about embedded videos or facebook. I need this to work on Youtube.com.
I need a solution that won't break Pandora (or that can be easily enabled/disabled).
