A way to differentiate a private browsing windows

[pixelsingrey]

Hello. Right now when opening the Private tab, the only way to differentiate it from your Profile one is the huge banner when opening it for the first time. After that however there is little to practically no way to tell which window Im searching on unless I remember what tabs were open on each. There should be a small icon that lets us know if were in the Private browsing simmilar to what Firefox does
