Maybe this is a simpler check:

    strace /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/MiniBrowser
--enable-plugins=FALSE http://extensions.gnome.org 2> test.log
    fgrep mozilla test.log

It should show a "we cannot detect a running copy of gnome..."
accordingly, but strace shows it actually do something with the shared
plugins.
Why i claim here is that it actually loads the plugins (and probably
doesn't run their main hooks).
