Are you sure you're using Quantum? Quantum isn't in Firefox 57 for mobile, you need the beta 58 for Quantum.

Huh, I didn't know this. I felt Firefox 56 -> 57 was a major improvement in Android too, and was sure this was due to Quantum. I wonder now if that was just placebo.

It wasn't just placebo, some parts of Quantum made it in to 57 mobile, just not everything.
