I agree, this is confusing because the DllNotFoundException has the
full path to the .so file (from an Ubuntu DllMap I'd guess). However,
full paths don't (always?) seem to work with DllImports. You need to
add /usr/lib/firefox to the LD_LIBRARY_PATH environment variable
before you start the app so that the dynamic linker can find the
library.

The reason that is works from within MonoDevelop is that MD sets the
LD_LIBRARY_PATH for GtkMozEmbed already in its own launch script. If
you look in the MD launch script you can find some nice Gecko
autodetection code that you're welcome to use...
