For the figures in firefox, the placeholder height is excluding the height of figurecaption making the alignment go wrong. To reproduce, try any page in Firefox, inspect the height of the placeholder section corresponding to figure. It will be less than the actual figure.
Looks like a bug in Firefox. Upstream bug https://bugzilla.mozilla.org/show_bug.cgi?id=1043294
