On my office computer, private browsing windows have a mask icon on the upper right, but on my home computer there is none. Both operate in Windows 7. It's not a problem, but I do like seeing the icon to remind me that I am using private browsing.

As you know, Firefox has two different menus: orange Firefox button (compact menu) or full width classic menu bar.

I don't use much private browsing, but this is my understanding of how the indicators work in Firefox 20 and later:

Compact menusClassic menu bar
Regular session > New private windowPurple Firefox button with a maskPurple mask appears at right end of the menu bar
Automatic or permanent private browsingOrange Firefox button with no maskRegular menu bar with no mask

Is that consistent with your experience?
