I'd made a few themes in Firefox color on one computer, but when I went on my laptop, I didn't have access to them, even though I have sync on, so I published them privately because I want to use them on my laptop, but I still can't apply the themes to my browser. When I go to the developer hub, because that's where the email I was sent took me, there's no way to use the themes. Every time I look up "how to use private themes" it's about using themes in private browsers, and not themes published privately, so I'm at the end of my rope.
