Is this message being spammed persistently, or only during start-up?
Which web page are you loading, a blank page or the (default) Firefox home page?
Can you attach your about:support please?

I'm not sure if a debug build is supported, in the sense that it's guaranteed to run warning- and assert-free and promised to stay that way.
