Flex: Switching the debug default browser

I've started working in Flex quite a bit now. One of things that has bothered me is Flex always launches a debug window in Internet Explorer. I've been having some problems with the browser and would like to use something different, but couldn't figure out how to switch it. Someone showed me how this morning.

1) Goto Window => Preferences

2) Goto General => Web Browser

3) Select the browser you want to launch in the "External Web browsers" window.

Now your debug session should launch in your browser of choice.
