Web object failing to load a page in Google Chrome & Firefox

We are trying to redesign a required student activity that around ~3,000 students a semester complete using Articulate Storyline 360.

However, in our prototype the web object is failing to open a page they are told to open when in a Google Chrome or Firefox browser. This failure does not happen in Internet explorer. 

I am including the draft link here: https://lo.library.wisc.edu/evaluating_search_results/story_html5.html 

(there are 6 title slides in a row, our production student was playing with potential designs).

If you navigate beyond the title and introduction slide it will open a web object with a side navigation. Students at one point are asked to follow a few steps and then open "Academic Search" which is a database. In internet explore this works perfectly. In Google Chrome and Firefox it says that you have to allow unsafe script, then you have to reload the activity and re-navigate to this page for it to work. I even tried separating the web objects into two so that the database would load on its own and this is still happening. Is there a way to make this work so that students don't have to reload the entire activity?

This is urgent.
