Firefox wont display files stored locally on computer (Like images, css stylesheets)

I am trying to test my code for a website that I have stored on my computer (opening the .html files that i have saved on my computer in firefox) and when I view it in firefox, firefox does not display any pictures, stylesheets. I think this means firefox cannot find the files stored on my computer??? I refer to the the right way, and chrome, edge, ie, will work fine! Please let me know if ive not been clear enough. im sure im doing something wrong so please help! im just learning so its kind of hard for me to figure out what i need to do!

Thanks!
