OK, so I am using FireFox 5.0. And every time I click a Youtube video, I get this error message:

[Javascript Application] error.BVDCORE.videoFormats is undefined


Can anyone tell me how to fix it? The video works fine, it's just extremely annoying to have to close it every time I click a video. Is there a way I can fix it easily or disable JUST THAT error message? And, if possible, telling me why it is saying this? It's never happened before. I've googled this error, and got literally 0 results. Help? This ONLY happens on FireFox. I checked yIE and it didn't come up with that.

You are getting this error because of Youtube Video Downloader. Go to Tools>Add-On's. Now click disable next to Youtube Video Downloader Now Reset Firefox and it should work fine.

kingp1ng: I had both Easy Youtube Video Downloader and NewTabKing. Both stopped working. Uninstalled both. Problem fixed.

ice792: Try Video DownloadHelper 4.9.3 Really easy to use, you´ll get used to it quickly.

Taken from: https://support.mozilla.com/en-US/questions/856001

Check and tell if its working.
