[Trisquel-users] Webm, A Browser, and youtube?

[Dave Hunt]

Hi, I'm running I18N Edition, with all updates as of Monday, Oct. 24.  As I understand it, appending '&webm=1' to youtube links is supposed to cause youtube to present the indicated videos in a webm player.  Does A Browser support this?  Do I need extensions or plugins?  I've tried using Flash Video Replacer extension, but most of my selected videos will not play.  The extension passes bad links to totem. Thanks, Dave
