In Intern 4.x and 5-pre, the pre-set feature capabilities, used when fixSessionCapabilities is not false, are incorrect for current versions of Firefox. For example, Firefox + geckodriver supports mouse commands such as /moveto, but the brokenMouseEvents flag is set, so moveMouseTo ends up using simulated events unnecessarily.
Re-evaluate the presets for Firefox, and either fix or disable them for current Firefox (which may not need presets).
