Backing up Everything from firefox

[A_Mediocre_Kangaroo_Farmer]

I'm going to upgrade my system and as a requirement I will have to leave my w7 behind. I intend to do a fresh install of w10 and would like to keep my firefox just the way it is. Is it as easy as just copying the "C:\Program Files (x86)\Mozilla Firefox" folder and pasting it back in place once I've installed w10?

Normally I'd agree but All I find is ways to export bookmarks, or cookies, or profiles. I want everything. So instead of doing them seperate I figured I might aswell ask if this does the trick.

There used to be addon called FEBE for making backups of everything you want. Addons, bookmarks, settings, themes and so on. Its legacy and not supported by new version. I don't know if there's working version in development or some alternative. Besides making copy of ApppData/Roaming/Mozilla/Firefox/profiles/<profile>/ folder, I think Firefox's own sync is only feasible option. It gets addons, bookmarks and maybe settings too. But my 2 PCs are running different versions of browser itself so I can't say how much of theme and settings are carried over. I used FEBE to setup laptops browser.
