I use multiple Firefox profiles. I would like an EASY way to see the name of the Firefox profile somewhere on the screen. The attached image shows a theme I created which shows the name of the profile on the menu bar. I forgot exactly how I did it, but it involved typing this in a Word document, taking a screenshot and turning it into a jpeg, crop the image, upload it as a theme, then test it. Repeated several times until I got it to work.

I don't need or want fancy graphics here. I just need the name of the Firefox profile to appear somewhere in the window. In my fantasy world, there would be an option to include this name in the window Title bar.
