Environment

Enforce Server, 16.0 RU2

Seen after upgrading from 16.0 GA

Cause

This is due to a known Firefox bug:

Firefox still read old library file (.js) even if it updated | Firefox Support Forum | Mozilla Support

Firefox has an aggressive way to optimize performance.

All the js, css files only load the first time and as long as the file name and path not change the file won't get updated.

 

Resolution

The easiest workaround is ctrl+F5 (or other hot key combo in non-Windows OS) to force a reload of the page.

Another workaround is clear the browser cache:
