I found a probable source for the bug:  module unload before call..  See https://github.com/motin/taar-experiment-v2-shield-study/issues/15

This issue is no longer reproducible with the latest version of the "TAAR Experiment" add-on (1.0.7) installed, on the latest Firefox release (58.0.2). Verified on Windows 10 x64, Ubuntu 14.04 x64, and Mac 10.12.
