For the past while, Firefox on my machine at work, as well as both of my machines at home, refuses to play any more than 2 seconds worth of video on YouTube. It doesn't matter whether I'm actually on YouTube, or trying to play an embedded video, the result is the same: Video starts and then stops at 2 seconds. In the mean time, the cache indicator is marching across the screen, so you know that the video is streaming from YouTube, but the Flash player is frozen.
I tried many different fixes like clearing Firefox's cache, disabling and removing the Real Player add-in. No luck, until today.
Seems that QuickTime has some sort of hook into Firefox to allow itself to start playing videos as soon as a network connection is made, rather than spooling a small amount before playing.
I followed these instructions, and it now appears as though Firefox and YouTube play well together again.
- Start Menu > Programs > QuickTime > QuickTime Player
- Edit > Preferences > QuickTime Preferences > Streaming
- Look at the second box where it says Enable Instant-On and remove the check mark from this box.
- Click Apply and then OK.
- Restart Firefox
I need my YouTube...
