This has been happening a lot lately, mostly on YouTube. I don't know if it's YouTube, Adobe Flash or Firefox:
Gray exclamation mark

This will happen even half-way through playing a video, it will randomly turn into this image. I have to restart Firefox to continue to play YouTube videos.

  • Are you using the latest version of Firefox & the Flash plug-in? Does it happen just on Firefox or all browsers? Just on YouTube or other sites too? Feb 7, 2011 at 7:31
  • Is there a tooltip when you hover over the exclamation mark?

  • @Barry latest version of Firefox and Flash as far as I know. I try to keep up to date.

It is accused of being a bug (of certain versions of Flash Player) and an out of memory notification.

It's your Adobe Flash.

Try restarting your browser. Then go back to youtube.com and try to update your Java/Adobe/default Flash program.

  • It happens to me across multiple PCs, OSes, and browsers. It also happens whether I'm using html5 or flash for youtube. I don't want to flat out call you wrong, but I'm quite sure you are.

If it's happening across platforms and regardles of video accelerator than it is clearly a YouTube problem and not specific to one's PC or OS.


I think it's Firefox. This happened to me on Google Chrome, and the grey excalimation mark happened on YouTube, and another site I was watching an anime on. I tried YouTube on Internet Explorer, and it works fine.

I suggest uninstalling and reinstalling Firefox.


Most likely it's Adobe Flash as others have stated. If restarting doesn't help I suggest switching to HTML5 on YouTube. You can do this by following the following link: http://www.youtube.com/html5

Good Luck!
