Is there any way to stop HTML5 videos from starting automatically when
the page loads with YouTube? Flashblock is not working very well with
YouTube and SeaMonkey. Surely there must be some setting in
about:config that would either prevent autostart of HTML5, or
alternatively, force YouTube to send Flash instead.
I have the PrefBar extension from
<https://addons.mozilla.org/en-US/seamonkey/addon/prefbar/>. I created
a checkbox for PrefBar to toggle the preference variable
media.autoplay.enabled between "true" and "false".
This does not necessarily cause a Web site to send Flash in place of
HTML5 media, but it does allow me to block the playing of HTML5 media.
Also, FlashBlock does have an option to block HTML5 media.
I tried both of those things. Setting media.autoplay.enabled to false
had no effect on YouTube. Flashblock blocking HTML5 blocked it totally
on YouTube, so I had to turn it off to get anything from YouTube.
