How to migrate between Windows 10 profiles?

To correct a problem in MS Word, Microsoft Support created a new Windows 10 profile on my laptop and reinstalled MS Office. Firefox is still on my laptop in the new profile, but its appearance is changed. It has lost all the profile data from the old Win 10 profile. I have looked at the articles under "Manage preferences and add-ons" but I don't think they solve my issue because I don't have a backup of my Firefox profile. Or, if I still do, I don't know how to find it on the old Windows profile, which is still on my laptop.

I had a lot of bookmarks, add-ons and preferences that I would like to retrieve for my browser. Is that possible?

Sorry, what I meant was: Open the old profile folder, Copy it as is. Then open the new profile folder and Paste it in.

If you know the old profile name you can go to:

C:\Users\{Old Profile Name}\AppData\Roaming\Mozilla\Firefox\Profiles

And copy the profile: Is like this {name}.default

Thanks, AndRo Marian. I found three profiles there. The correct one is likely the one dated 12/6/2018. I can copy it and paste, but what exactly do I copy?

Please see the attached image. Do I copy "Is like this svwsn4sn.default"? What do I do with the "-1537366687475" that follows "default"?

And where do I paste the copy?

Copy the whole old profile As Is. Then Paste into the new profile.

Note: You may need to overwrite current files.

Thanks, Fred. I copied the old profile, folder and name, as a unit to the new profile folder (see attachment for result) and the system responded with the "Profile Missing" dialog. What am I doing wrong?
