I read the first suggested article before posting this question, but it wasn't specific enough so I was forced to comment, "This article fails to specify use of the backed up file in the event of a system/HDD reformat." The article reveals that the profile folder name must match (match WHAT in this scenario?), but does not reveal if any of the files within the profile have that specific identification embedded in them [which might result in logical error or error messages, and failure to accomplish desired goal]. It also does not say if all I want to do is back up the cookies, whether or not will backing up cookies.sqlite and placing it in the new default profile after the system reinstallation/hard drive reformat work.

Let me get more general in the event I'm not communicating what I wish to: I don't want to use a confusing, perhaps badly-written Firefox add-on to do this. I have a few secure sites I visit that give me a really hard time when I update or reformat, like my bank and NetFlix. Both parties CLAIM that I am "attempting to access your account from a different computer," but their security protocol writers are MORONS and liars, because it is NOT a different computer; instead of storing the STATIC MAC address of my computer, which DOES identify the specific computer attempting access, they store a number of different bits of data which are VOLATILE and DYNAMIC [in cookies], and I have to go through this bullcrap of accessing my email account and entering in a verifying one-time-use code to get to my own [epithet for solid waste matter]. So, will I be able to do what I want just by manually backing up cookies.sqlite and placing it in the appropriate directory when needed? It should be a very simple matter for these idiot security experts to query systems for the MAC addresses or to get users to supply it manually (it's easy to find), but NO! That would make SENSE, be EASY, and MORE EFFECTIVELY MANAGE THE SECURE NETWORKS. My idiot bank does not even allow the use of special characters necessary for the creation of sophisticated passwords [that would take over a quintillion years to hack via a Brute Force attack].
