While awaiting response here, I inadvertently created a new profile. Now, there might have been a program update; but my windows under this new profile have a blue quality. Anyway, I found saved profiled and copied them to a new folder on my Desktop so they would be easy to find. Now, I need a way to upload one of them. Concurrently, there is another problem. When I click on About Firefox, the box says "Firefox is being updated in another instance." Do these problems affect one another?

This post is through my Firefox app from the Microsoft store. Having saved so many Profile files, I am going for a new installation. My current one seems too buggered up.
