What to do if you upgraded to Google Chrome 5 and the Flash Debugger doesn’t work

I updated to the latest beta of Google Chrome, and suddenly my Flex Debugger stopped working. The progress bar read “Waiting for Adobe Flash Player to connect to debugger…”, and after a minute or so it timed out with the error:

Failed to connect; session timed out.
Ensure that:
1. You compiled your Flash application with debugging on.
2. You are running the debugger version of Flash Player.

I had the debugger version installed, but it turns out that Chrome now has an integrated version of Flash that is not the debugger version.

The fix is actually pretty simple. In Chrome, just type the following URL into your address bar,


and click Disable under the Shockwave Flash plugin with the location that ends with “Flash Player Plugin for Chrome.plugin”. You will want to keep the other Flash plugin enabled because that is your debugger version.
