Hi all, I was following some mozilla bugs related to Windows 64 bits support. IIRC, those were interesting for JBoss Tools VPE or BrowserSim at some point, however, I cannot remember the details. Anyway, some of those bugs were marked as fixed recently, such as https://bugzilla.mozilla.org/show_bug.cgi?id=482143#c15 . Not sure whether this is any helpful for us, but I thought it might be worth sharing.
