Firefox plugin to disable / block WebM video

I'm accustomed to using the FlashBlock plugin to disable those annoying advertisements that play automatically, but I'm unaware of any available plugin that accomplishes the same thing with WebM content. Any suggestions?

Thanks for the suggestion. This solution would be more permanent than I would like; the FlashBlock plugin has everything blocked by default, but allows one to click on anything you want to un-block. This is why I was hoping for a similar plugin. – None – 2011-04-23T22:40:16.313

@Withnail If you already have Greasemonkey installed there are some other tricks you can do, like allowing the video to be visible but disabling autoplay. Have a look on this page, there's a User Script near the bottom.

Thank you for the help. I'm going to leave this one open for now, until someone runs across a Firefox plugin. – None – 2011-04-25T19:15:06.593

Much obliged! Perhaps you could turn the comment into the answer so I can accept it? – Withnail – 2011-04-28T04:27:01.530

@Magicianeer Yeah, looks like you've found the same bug I did too. If you write an extensions let me know and I'll update the answer.

I decided to kill HTML5 totally in my Firefox, until flashblock supports it; and I'm trying to bribe the flashblock developers with my hard-earned cash...

meanwhile:

about:config
search: media.
media.autoplay.enabled = false
media.ogg.enabled = false
media.wav.enabled = false
media.webm.enabled = false

Now, tell me how to do it in chrome!

You could also use media.autoplay.enabled = false by itself, but Youtube cheats its way around that, so need this add-on too:

See also: http://rubenerd.com/noscript-html5/ but I think noscript permanently disables the videos, no click-to-play; can only white-list the whole site.

I have written an answer for this that should apply to all videos. It's basically a native feature available in Firefox Nightly (but also hopefully in the stable channel soon).
