AIR not starting on OS X

Hi

I'm running under OS X 10.9.5 and I can't run any AIR app anymore.

I've see this topic :

Adobe Air not working on Mac since OS X Yosemite upgrade

But compiling my apps with either the latest AIR SDK 15 or AIR SDK 16 beta doesn't change anything.

I've also seen a topic on stackoverflow where someone add a similar problem because of the use of FlashBug extension for Firefox:

I also have that extension installed but I renamed all my m.cfg files to mm_backup.cfg file but it did not solve the problem.

Wether I try to start an app from Flash builder (Run as desktop app) or by launching a released app or by using the adl command, it just fails silently...

What could be the reason of my problem ?

Thanks

Thomas
