The situation didn't change with this another version of Firefox for Android (and I have all of them): 1) A webpage with many and mostly made out of grid and flex elements does tender waaaaay too slowly and ugly (low quality artifacts on scrolling) 2) Animations like of the mere max-height to unhide content perform like garbage, as if it was performed by the CPU alone And I already did report this behaviour even with this version, let's see how it will turn out. Out of this experience, expecting mobile web apps to perform well enough is meaningless, lag and rendering artifacts will fill your patience meanwhile on Chrome like browsers everything is waaaay smoother.
