I was running into the same issue with Firefox 4 crashing. When I
built Firefox with debugging turned on, I couldn't get it to crash. So
I don't think it will help in this scenario, but you could give it
shot I suppose.

I finally wound up removing and reinstalling Firefox, the linux compat
layer (f10), the flash plugin, nspluginwrapper, and every trace of the
plugin from my system (that I could find). I also followed the
Handbook's recommended installation method, and began running "tests".
The testing phase was simply opening many tabs with embedded flash
objects :)

So far, no crash. The only message I continue to see in the terminal
from which Firefox is launched is:

*** NSPlugin Wrapper *** ERROR: no valid NPP -> PluginInstance mapping found

It doesn't seem to cause any real problems, so...

Anyway, I'm going to keep hammering until something finally breaks, haha ^_^
