+WebKit local storage
+====================
+
+WebKit does create files in your $XDG_* directories, i.e. ~/.local/share
+or ~/.cache. It's up to you what you want to do with this junk. I remove
+it regularly if no WebKit browser is running. Another option would be to
+change the $XDG_* variables.
+
+I have explicitly not turned off the local storage feature in WebKit
+because I don't know if this breaks web applications.
