How to Fix : Adobe Flash Player 9 - Where is the debugger or host application running?

Sometimes when i visited a website/blog, then scrolled about 2/3 of the way down the page a dialog box appeared in the top right of my screen that said "where is the local debugger or local host application running?" :

Adobe Flash Player 9
Where is the debugger or host application running?
o Localhost
o Other Machine
Enter IP Address:

I didn't know why it appeared, i thought it was probably because of an error on the site i visited, so i just cancelled it, and it would just disappeared, Firefox has stopped working dialogue box. Unfortunately, it didn't happen once, On other sites, I also randomly got that prompt. It irritated me!

After blogwalking and searching on Google, i found the answer why it happened and the solution. According to some sources i read, It could be a sign of a corrupted flash player 9 install, OR a flash player 9 installation that is missing components, OR user configuration.

How to resolve this broken adobe flash player 9 problem ?!

>> SOLUTION (Fixed my problem!)

+ If your being prompted with this dialog box in Firefox, Download and install Flash Player 9 Plugin content debugger (for Netscape-compatible browsers)
+ If your being prompted with this dialog box in Internet Explorer, Download and install Flash Player 9 ActiveX control content debugger (for IE).

Good Luck!

Im a flash developper, and im telling you that it is not a bug but a configuration of the swf (flash) file generated by the webmaster. He lets the option "debugger" on when he shouldn't have.

I get the same error on ESPN. So a lot of websites are screwing up I guess.

After 4 sites, you have the first real solution to this problem. Thank you for your post!

To the comment above: "I'm a Flash developer and the developers are messing up" - Can you explain how if this error is caused developers, why was it not an issue until Windows 7?

I'm a developer myself: I feel it clearly sprang up upon the release of Win 7. ITS A BUG.
