Security Error: Content on about:tab may not load or link file

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

It would be simplest to place the image file in the chrome folder alongside userContent.css. Does that work, or does that also trigger an error?

Somehow that worked. It now loads my image correctly, like it did before. Wish I understood what changed to make the userContent.css work that way. Regardless, thank you for your help.
