I'm on a Win10 Pro 64-bit Lenovo laptop. FF private opens fine using Ctrl+Shift+P or clicking on New Private Window in the menu, but I'm trying to create a desktop shortcut that opens an FF private window. Everything that I've read says to simply add a space and then "-private" to the Target line in the shortcut properties. However, when I use the shortcut, a regular browser window opens with my Google account logged in and search history available.
