Unfortunately no. The bug is old, and his mind generally fixes not even trying.
Here's my question on SO from February last year stackoverflow.com/questions/28751990/firefox-bug-w...
He asked he somehow hacked (in the comments explained + in the last comment the link to the demo, there seems also comments).
I've done a lot of demos with 3D transformations and multiple attachment elements with transform-style: preserve-3d and each time stepping on the same rake. Here's another demo, where the hack did not work, in the end, in FF everything is broken - codepen.io/suez/pen/WvaKpy
And then people keep saying that FF is a good browser for web developers, that makes me sick laugh.
As for your particular situation, you just have to avoid nesting the items and divide them according to their individual containers with the prospect, and so on. Then you have no reason to keep 3 units in 1 container, just make 3 of the container, set the desired z-index, but within each make 3D effect and they couldn't be with each other intersect. All with transforms, z-index and combination of other properties often have problems, the easiest way of fixing this is increasing the number of wrapper containers. Too lazy to go into details, just believe me naslovo, I have a lot of experience of suffering in this area :)
