How to display a folder knowing its path

I don't think this is possible. I looked at a list of Safari Extensions, and no extension I found has this ability.

NOTE: If you put the actual URL path description in the Safari address bar, ex: file:///Users/Panoy, Safari will open a Finder window to that path, not display the path in the browser window itself.

Try doing this:

1. Delete the sidebar shortcut of johndoe
2. Press ⌘ + ⇧ + G
3. Enter /Users/johndoe into the textbox
4. Press Go
5. Now drag the home icon at the top of the fider window to the sidebar

Or try right clicking on the home folder and click open in new window
