I haven't done these tricks myself, but I know that some activities
ship executables and libraries inside their bundles.

Two places to look at are modifying PATH and LD_LIBRARY_PATH and
insert in them paths inside the bundle.

Also, you can set some mozilla-related paths at startup, see hulahop.startup().

Would this be enough?

strace -e open may be helpful in seeing which files it looks for and
fails to find.
