Image Upload/Image Settings Issues

Hey guys, I know there is a how-to directly above but that didn’t help and I’m thinking it might not be the same thing, so here I go.
I’ve just updated to 2.8, never had ANY problems with the prior version and I went to upload a new photo but the box wouldn’t popup, I then tried to click an image option box and that didn’t pop up either- though the grey screen covered in low opacity. Incase that makes no sense to you, here. https://i41.tinypic.com/5plk3o.jpg
I use a Firefox on a Mac laptop, but I don’t see why all of a sudden issues would arise with this? I tried it on my sisters macbook also and it was the same so it can’t be just me being stupid. If anyone has any idea I’d be so very grateful. Thank you.
