Recently I was watching videos on YouTube, everything was working fine, and all of sudden it started giving problems. A message popped up saying “Hello, you either have JavaScript turned off or an old version of Adobe’s Flash Player“.

It was kinda strange because I had not changed any setting. I was sure that JavaScript was running fine and also had latest version of Adobe. Rare chances were that YouTube upgraded Adobe requirement when I was changing from one video to another, like one in million times it could happen !

I upgraded to the latest version of Adobe and as suspected that was not the problem. Frankly I still don’t know what the problem is, but this trick helped me :

I use Firefox and clearing the cache and private data helped me set this problem. The clear Private data, Go to Tools –> Clear Priavte Data –> Clear Private Data Now.

This trick worked for me. It’s not necessary that this will work for everyone. Here are some other solutions I found on a couple of forums, try these if the above trick does not work for you.

One solution is if you have an Anti-Virus like Norton Anti Virus or try turning off the Ad and Popup Blocker and reboot your machine. Try running youTube again, this has worked for a few.

For Downloading the ‘complete‘ version of Adobe Macromedia Flash player solves the problem, which can be downloaded it from :

If any of the above works or if you have any concrete solution which works for everyone please share it.
