Started hitting this today after bug 1195180 landed. I've confirmed that dropping --disable-accessibility from my .mozconfig fixes it. mozilla-central\objdir-fx-64\dist\include\mozilla/dom/DocumentTimeline.h(48) : error C3668: 'mozilla::dom::DocumentTimeline::GetTickCount' : method with override specifier 'override' did not override any base class methods
Created attachment 8667276 [details] [diff] [review] possible patch Various other files that use GetCurrentTime (like AnimationTimeline.h) have a check for GetCurrentTime and undef it if set. Doing the same in DocumentTimeline.h fixes the bustage for me.
