How to disable flash debugger Error Messages in FireFox

If you have the flash debugger installed or have Flash or Flex builder you will get annoying error messages from many of the websites that you visit today where developers have errors in their flash applications.

You can disable this by creating a file mm.cfg under your users settings folder

c:\users\\mm.cfg

Windows XP:

c:\Documents and Settings\

OS X:

/Library/Application Support/Macromedia

Enter this in this file and save it.

SuppressDebuggerExceptionDialogs=1

Restart Firefox and the errors will no longer show.
If you need to display the debugger error messages set the value to:

SuppressDebuggerExceptionDialogs=0
