This is why I do most developing in Firefox

As for a lot of my testing needs, i often need to use private browsing. These are my 3 browsers, first regular, then their Private/Incognito/InPrivate (LOL Edge developers combining them). Clearly Firefox makes it the easiest to tell which is which... At least for Edge, they add \[InPrivate...\] to the end of the task's title, as long as the site's title is really short like this sample image, you can see it. Why can't the other two give you a more visible distinction for those of us who may have many windows open at once... LOL
