Aims and Methods of Scouts BSA has a learning page you cannot bypass

I am using Firefox, which I have used for all training without issue. Go to the Table of Contents and select Methods of Scouting, and then Leadership. When completing this screen, there is no option to Continue, Back, etc. you are just stuck. I bypassed it by using the table of contents to continue navigating.

The preferred browsers for Training are Chrome and MS Edge.
