The first is the IE Plug-in,

Download the Windows Flash Player 10.2 ActiveX control content debugger (for IE) (exe, 2.99 MB)

The second is the Firefox plug-in,

Download the Windows Flash Player 10.2 plugin content debugger (For Netscape-compatible browsers) (exe, 2.95 MB)

After the above two plug-ins are installed, you can use IE and Firefox for debugging.

 

The third version should be the desktop version.

Download the Windows Flash Player 10.2 projector content debugger (exe, 6.36 MB)

 

 

For IE or Firefox, choose Window> preference> General> Web browser.

I installed chrome Firefox IE, but there is no chrome in the selection. However, to debug SWF with chrome, you also need to install the plug-in for Netscape-compatible browsers.
