I haven't got the faintest idea what happened, but since about 3-4 days now I can't play any clips on YouTube properly at all.
Proper as in continuously without loading, pause, playback, pause, loading, playback, pause, loading, playback, etc.
What on earth happened? Is it me, or is it YouTube? I'm using Firefox 3.6 Beta 5. But the issue is the same on Chrome as well as on Internet Explorer.
