Hello, I have this problem. Recently I noticed, that when I try to change the quality of the video from the default 360p to whatever one, the quality will jump to 240p and the video wont run. There will be just black screen. I tried resetting the browser and it did not fix my problem. I tried the same video in internet explorer and the quality change worked normally.

How could I fix this?

Thanks

Dear, Everyone who cares. I've had the same solution on and off for weeks, and I have just now found my solution. Try LOGGING OFF. Something in the account settings was doing it for me, but Logging off of my youtube / gmail account fixed this problem.

Spread the word.

Logging off causes YouTube (Google) to remove/reset some cookies, so this still sounds like a cookie issue and either you have/had corrupted cookies or otherwise have cookie problems.

Download , and reinstall Java 7 Update 51.

It has worked for me

Updating Java doesn't have anything to do with playing media files on YouTube, so something else must have caused this to work (clearing YouTube cookies or clearing local storage used by YouTube).

To avoid confusion:
