Holy simplicity!

I love it! Works as advertised. Makes it clear that you're in a private window. Beautiful purple shades as well :)

Good idea but it also changed the tab colours, address bar colours and menu colours in non-private window.

Was great when published, but some colours in non-private windows get changed as well (set to black in a light theme). Presumably due to some changes in Firefox after the add-on was last updated.

Works perfectly!

Fajnie pasuje do trybu prywatnego.
