When you go to a website with a file uploader you click on a
choose file and a pop up window appears with a sidebar similar to what you have in your standard finder window, however recently all of the options like Documents, Downloads, Pictures etc are no longer present, now I can only see ak52-macbook and remote disk. In standard finder windows I have all my standard folders plus custom ones that I added. I made sure in finder preferences that all of them are displayed.
I could not find anything in the finder or chrome browser preferences regarding this so here is my question, how do I display all of those folder in the pick file to upload pop up sidebar?
