Data embedded in "object" tag is not loaded, depending on which Firefox profile I use. What setting controls this?

In Firefox 115.8.0esr on linux RHEL7, I am loading a local html page (using file:///...) that I created. Inside the html page, I have a tag "<object id="hiddenDataObj" data="abc.txt">" where abc.txt is a text file in the same directory as the html file. Using my default profile, the data is loaded and some downstream javascript runs as expected. When I use an alternate profile and try to load the exact same page, I get a javacscript error "Uncaught TypeError: hiddenDataObj.contentDocument is null." It is not null when I run my default profile.

I'm trying to figure out what setting in my profile is enabling/disabling the loading of the data so that I can change it. I've gone to about:preferences and scrolled through and it seems like all settings I see are the same between the two profiles.

Thanks for any help.
