There are many ways to set the profile directory, you could use the
dirserviceprovider goop, but you probably don't want to do that in this
case. The simplest way to select a profile from embedded code is to:

1) Install a directory service provider that responds to "ProfD"
2) Send appropriate observer-service notifications to notify gecko that
there is a profile. In this case, you can see what the Firefox startup code
does here:

http://lxr.mozilla.org/mozilla/source/toolkit/xre/nsXREDirProvider.cpp#666

3) when it is time to shutdown, you do this process in reverse: you fire
profile-shutdown notifications
http://lxr.mozilla.org/mozilla/source/toolkit/xre/nsXREDirProvider.cpp#709

4) and then uninstall your directory provider

That is not true, MOZ_SINGLE_PROFILE is defined in all toolkit-based
applications (which includes Firefox), no matter whether they are built
statically or dynamically.

No, this is not possible.
