I just got a new laptop because my old motherboard fried on my desktop. The old master drive is fine and I have a transfer kit that I can use to transfer over whatever files I need. I cannot figure out how to transfer my Firefox profile over to the new laptop. I cannot locate where the files are that I would need to transfer and don't know which files those would be. Only article I could find on here requires being able to either launch Firefox or the OS. I can't do either so help please.

Thanks!

You need to take ownership of the files if you do not have the permission to copy the files. You need to do that while running Windows Explorer as Administrator.

Okay located the files, but now I keep getting an error every time I try to copy them over saying that I need administrative permission. Both are my computers so not like anyone else could have administrative permission so really not sure what I can do from here.

I did that and still getting the same error. I doubled checked the files to ensure I have ownership and still the same thing.
