SL360 content running in latest Firefox browser shows several JavaScript errors and not in other browsers

I created a simple Articulate Storyline 360 3.50.24832.0 page and then published it both as SCORM 1.2 and SCORM 2014 packages.

When I launch the same content in Firefox (87) I see several errors in our LMS as well as in, such as:

  1. downloadable font: kern: nTables is zero (font-family: "ArticulateBold CharBold153FC30F" style:normal weight:400 stretch:100 src index:0) source: data:application/font-woff;
  2. Uncaught TypeError: n is not a function (in slides.min.js:2:209734)

These errors do not occur in Chromium based browsers - like Microsoft Edge - and interfere with out other JavaScripts. 

Any suggestions how to prevent these errors in Firefox? 

NOTE:  I found similar JavaScript errors with Articulate Presenter content running in Firefox. But Articulate Rise content has no issues in Firefox.
