Youtube Error Message - Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player, Possible Solution

Thursday, April 2, 2009

I was hitting the walls before finding the solution for this unusual error message from youtube when viewing some videos from Windows, mostly movies, the error message is

Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player.

After crosschecking browser javascript settings, I found that javascript is not disabled in my Firefox or IE7, then I installed the latest flash player as suggested above which doesn't solve the problem as well, finally suspected whether the Symantec Firewall installed in my system may be the reason for this error as many a times I visit a website with ActiveX control, it prompts me "The Web page you are trying to view contains an ActiveX control." and the action suggested by Symantec Firewall is Block Once ("Recommended"), but in this case when viewing the youtube video which flashes the above error, the symantec firewall doesn't prompt anything.

So the solution to get rid of the above error is to temporarily disable the Symantec firewall as shown below (right click Symantec Firewall in the desktop tray, click Disable Symantec Firewall for 5 minutes, the least time you can disable the Symantec firewall), although its not advised, its the only hot fix I found to get rid of the above error message although I am still exploring another way to fix the above error by changing Symantec firewall settings to trust the content from youtube, in general firewall may be the reason which may block some youtube videos with the above error message.

But still the unanswered question is why the Symantec firewall didn't prompt before viewing these videos, lets leave it for a future discussion.

I've been having this problem too, and traced it down to the Ad Blocker in my Symantec Client Firewall. I'm still trying to figure out the proper settings to allow the videos to play, while still keeping other stuff blocked.

Yes, just as Danno said, it's the ad blocker that is the culprit. i don't like leaving it off, so if we can figure out a set of permissions for youtube and its (evil) ad affiliates that would fix the problem
