Is there any way to get Flex Builder to connect to an existing browser session running Flash Player Debugger? I can connect to FDB like this, but with Builder I need to click Debug and rush to close the newly opened browser window before it loads the Flash file and then go back to the session I want to connect and right click it to start the debugger. Unfortunately this is not very reliable as I can't always beat the window opening, requiring several attempts before being able to connect to the session I am interested in. If I could just tell Builder 'Start debugging' and then have it wait for the connection, I could now calmly go over to the browser, right click, hit debug, provide the IP and voila. This would allow me to inspect variables on a hard to replicate bug on a session running on a tester's computer.
R – Make Flex Builder debugger start listening for incoming debug session connections

As mentioned in the other answers, you can modify the launch configuration to refer to any URL that doesn't contain a SWF; but I just wanted to add that you can also use the URL "about:blank", which has the advantage that (as of Flash Builder 4) Flash Builder won't even bother opening a browser page -- it will just start listening on the socket.
