Smack dat

I know this is a bit of a dumb question and I did try Googling it but it just seemed easier to ask it here.

I have an old laptop running Windows 10. I also have a new laptop running Windows 10.
How can I backup and restore certain files.
For example, I need firefox, Chrome profiles with bookmarks.
My thunderbird with profiles.

Then all my programs like nifty stats, mass planner and a few other paid programs.

Of course any docs on the desktop, documents, pics and music etc.
