I have this issue a ton with YouTube, rarely with Google Video or CuteCast or any other flash I see. I use the latest version of Firefox. I also use the Firefox plugin Flashblock. It replaces all embedded flash with a clickable button, and when clicked, will load it. Useful for all those flash ads. This has been happening for several months now. I have had Flashblock installed for perhaps 2 years. This also happens regardless of if I allow YouTube or Google or whatever to have autoplay functionality in the browser.
I will choose to watch a video, and may see the first 5 seconds. Or the first 40 seconds. Or the first 4 minutes. Or perhaps the entire video. If I reload the page it will stop at the same point. Usually if I reloaded Firefox or rebooted the computer, it would reset and allow me to re-try (often successfully).
Now it is ‘sticking.’ I have rebooted twice, cleared my Temporary Internet Files (via Disk Cleanup utility), ctrl-F5d the videos, and I still get ‘stuck’ at the same points in the same videos. If I freeze in the middle or beginning of a video, the loading bar in YouTube/Google will also stop, although I can make it replay up to the same point.
If I load a freezing video in MSIE6, while it will re-download the content, it too freezes at the same spot.
What the heck is happening? How can I stop it? I’m happy to provide any other information desired.
