I was prompted to upgrade to Firefox 40 today, and as soon as I did that, I started having issues with video playback on YouTube and various other sites. The video was slow, the sound was all garbled. I have the latest version of Flash installed. Everything was working perfectly before the upgrade.

Just to see, I downgraded back to Firefox 39.0.3 and the playback issues were gone. So needless to say, I won't be upgrading anytime soon. Is this likely a Firefox issue, a Flash issue, an issue with my computer? I'm running Windows XP. Any help, thoughts would be appreciated.

Hi Dan, another XP user reported today that YouTube had switched to the HTML5 player for him, which does not work so well on XP.

There are at least two extensions to force YouTube to serve the Flash player, and perhaps one of these would work around the problem:

Thanks for the reply! I tried the first add on you listed, and it appears that has fixed the problem. My videos are playing normally again. Guess my system isn't ready for HTML5 yet. Appreciate the assistance.
