A1: RECOMMEND edit the plugins/org.eclipse.platform_4.2.*/css/e4_default_gtk.css and set the font-size to 9x or comment the font-size line out; see also very-large-tabs-in-eclipse-panes-on-ubuntu

    swt-mru-visible: false;

A2: install according to the E4 CSS light editor (Incubation) plug-in. You can find it in the eclipse market place. An add a css rule to override the default, e.g.:

.MPartStack {
    font-size: 9;
    swt-simple: false;
    swt-mru-visible: false;
