Ha, thanks for filing. The Flexbox inspector is enabled in nightly only, however in bug 1496439 I added tests that exercise it but do not switch on the pref. So on beta, these tests will fail because the tool is not enabled at all.
We need to force the pref to true before the tests run.
I'll do this.
