Firefox will not run videos on Youtube.com The 4.X beta version also will not run video. Any ideas on why all of a sudden videos won't play?

Make sure that your firewall isn't blocking the plugin-container process.

Thanks for the reply. Neither of these are the problem. I disabled my firewall and anti-virus. Still no video play. The browser just shows "Done" right away without playing the video. I checked all dom. settings in about:config - tried all as "false" and "true" no difference.

Any other ideas? I'm trying to run Firefox in safe mode but can't seem to get it to do that.

Need to run FireFox 4.0b11 in 32-bit mode for YouTube to work. On Mac, select Firefox in Finder and do "Get Info" and select "Run in 32-bit mode". Same fix for Safari not running YouTube videos also. Hope this helps.
