Simple Question: Setting Firefox

This may seem obvious but I remember I used to not know where to find file and stuff because they were never where they were for Windows OS. They're always at the very top of the screen, seperate from the actual window. I sometimes still forget this and can't find file and edit etc because they're not on the window, haha. Just always look at the very top and unless your in full screen mode whatever program is selected will show it's "File" "Edit" "View" "History" buttons.

To make a new folder, go into the folder you want by clicking the "finder" (should be the first emblem in the bottom dock) and then click the thing that looks like a cog (gear) looking thing, and select "New Folder"

You can also go to the desktop, click the desktop, click "Go" and navigate to the desired folder.
