I'm not able to reproduce this at all on my iPhone 6 (iOS 9.3.1) using 4.0 (build 11). I'm able to launch Firefox, open the tab tray and open and switch tabs perfectly fine. Works for me.

Any missing steps? Which device are you using? Reproducible on different devices? Not enough information here.

In the attached issue the following steps were followed:

Unfortunately I don't have the symbols for the crash log since it looks like it was taken off a master build. Is there a crash log for the 4.0.0b7 crash?

The issue occurs on 4.0.0b7 as well but no crash log is created on the beta version.
