I use Firefox to preview and upload animated ads that I build in Flash (with Sizmek plugin). WhenI go to preview my ad from Sizmek, I receive an error message 6 or 7 times and am then unable to preview my ad. I know that this is not a Flash update issue, because this ad is set to Flash Player 9 and because I am able to view the ad once I have uploaded it to our server. I simply am unable to preview in Firefox. I have taken a screen shot of the error messages, but there is no place to attach it here.
