Im in Moutain Lion and Firefox 23. Back in Snow Leopard, I could have the Finder and the Firefox app windows showing diferent sidebars. Let me explain, lest say I wanted to save a picture, a save-as window appears showing a finder sidebar. They used to be independent from each other, but now what I do in one affects the other. I choose to hide the "Devices" from Firefox save window, but I need to see them in the Finder. How do I make them independent?
