GNOME Bugzilla – Bug 751963
extensions.gnome.org/local/ should not show Delete (X) buttons for system-wide plugins

Some extensions come preinstalled by distros such as Fedora, and can only be deactivated, not deleted by the user. In that case, the red (X) buttons should not be shown in extensions.gnome.org/local/ — it is otherwise confusing to have a button that does nothing.
