Firefox launches slowly with Microsoft EMET EAF+

Firefox (latest version, 42 at the moment) launches very slowly with Microsoft's Enhanced Mitigation Toolkit installed (also latest version, 5.2 at the moment). More specifically, the issue is with the EAF+ protection feature. With EAF+ disabled, the issue disappears.

Is this an issue with EMET, or is it a bug in Firefox? If it is a bug, consider this a bug report.

I found this: https://social.technet.microsoft.com/.../firefox-takes-a-long-time-to-launch-with-eaf-enabled?forum=emet and it points to a work around and possible fix in the next beta version.
