Black photos when uploading

I am trying to upload images to my listing but they are showing black! Never had this before, images are small jpegs, 1920x1080 and i'm using firefox.

I could be wrong, but it looks like you're overriding Firefox's webpage background color setting. I've found that doing that makes some sites unusable. Ensure that the setting is set to "Never", like in the screenshot below:

I had the same problem, but Firefox often messes up layout, so I switched to Edge and the images appeared correctly.
