Thank you, Davehc. I changed the view settings as depicted. It did not change a thing. Still no C:\Users\username\AppData.
Thank you, Norton as well. I have no idea what it is that I am supposed to do.
Gentlemen, thank you for trying to help me. I do not have a computer science degree of any kind and have never coded in my life. The processes you depict for me demonstrate enormously that unless you know how to read and write programs in C++ or whatever language is used and are fully conversant in the technology language, there is no way one can decipher how things work, where they are and what needs to be done to make things work a simple way. Episodes like this, like for so many others like me, be they in the 20's or be they older, drive in the very fact that technology becomes synonymous with fright because if you do something wrong there may be a high chance that the whole thing will stop working if you do not know what you are doing. It is technology that is restricted to only the initiated, something intended by default and by consequence to PREVENT the uninitiated from doing things better and from automating what should have by now become easy.
I truly do appreciate your trying to help me but I do not have the technology education. At the moment, the only simple workable solution is to manually transfer each and every URL in my Edge Favorites to my Mozilla Favorites AND to keep a written document of what is in the favorites folders because those folders are nowhere to be found. It's depressing that something that should be so much simpler is so much more complicated than it should be. Favorites have existed for many, many, many years. It is a tool many of us use to try and facilitate our online research and activities. But in the end, because this automation process for Favorites is so crushingly impossible to use, it has in effect evolved to remain an intensely manual process. The opposite of its original intent to make things simpler.
I do mean it that I do appreciate that you are trying to help me. I do not have the proper technology education and experience to enter the forbidden city. I do not see myself spending several thousand $ getting a degree to understand how Favorites work in each iteration of Windows 10 and Edge and how to copy them from Edge to Mozilla. I give up. I have tried numerous web searches on how to do what I am trying to accomplish: automatically copy all of my Edge Favorites to the Mozilla Favorites. In vain. It's depressing to know that the only apparent method is to manually copy each URL into Mozilla Favorites AND keep a separate written record of these entries.
