Can't Run or Debug Air, new install FB4.5

[dhbrown]

I just installed CS5.5 with FB4.5.  This machine (Win7) also has Flex3 installed.  I tried importing a project from FB4.1 and it failed to run or debug.  When I request a debug, the console reports "[SWF] LTAWWall.swf - 8,746,129 bytes after decompression", but nothing else.  I can see that adl.exe shows up in the Windows Task Manager process list, but the app window never displays and no traces show up on the console.  No errors are thrown.  When run is requested, adl.exe launches silently and no window is opened.  Adl.exe stays in the process list until manually ended.

Then I unisntalled and reinstalled FB4.5.  Then I wrote the following:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                       xmlns:s="library://ns.adobe.com/flex/spark"
                       xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:TextArea text="Hello World" verticalCenter="0" horizontalCenter="0" />
</s:WindowedApplication>

Trying to run or debug this from FB results in the same behavior as before.  No window, no error messages.  Then I did an export build, ran the .air install file and it ran correctly.

Any advice on how to get this working would be greatly appreciated.

I have the same issue since I upgraded to FB 4.5.

I found this post with a possible solution, but it did not work for me: http://forums.adobe.com/message/3899680#3899680

Please let me know if you come up with any thing, and I'll do like wise.

Thanks for this pointer. The culprit, at least for me, seems to be the flashfirebug extension.  It is creating a entry in mm.cfg

"PreloadSWF=C:\Users\{user}\AppData\Roaming\Mozilla\Firefox\Profiles\4x152blf.default\extensions\flashfirebug@o-minds.com\chrome\content\flashfirebug\flashfirebug.swf"

By removing this I was able to get FB4.5.1 working (finally).  I uninstalled flashFireBug. In theory, you can customize the mm.cfg file that it creates (http://www.o-minds.com/products/flashfirebug#settings), but I don't have time to mess with that right now.  It may simply be incompatible.
