Restore bookmarks after PC failure
My desktop PC broke (hard drives are OK). I got a new PC with Windows 11 and the former C: drive is now the G: drive.
I installed Firefox and I need to get all my bookmarks back. I can find my old profile on the G: drive in .../appdata/local/Mozilla/Firefox/Profiles and I tried replacing the new Firefox profile on C: with the old one from the G: drive, but Firefox just keeps creating a new one and ignoring the old one.
There are years of bookmarks there I'd really like to get them back.
Help, Please?

cookies: cookies.sqlite Do not bother. Cookies will be created when you return to the website. However, you will have to log in everywhere. And you may lose any settings that websites store on your computer.
extensions(add-ons, themes): it would be better to download them fresh. If you need to remember what add-ons you had, open the extensions sub-folder and look at the .xpi files
logins.json and key3.db [v58+]key4.db : These are the password files. Copy Both !
persdict.dat : custom dictionary - words you added to the dictionary
mimeTypes.rdf [v55+]handlers.json : What to do with what type of file.
places.sqlite : History and Bookmarks.
prefs.js : Your settings. Note: If you were having problems, this could be contaminated.
cert8.db [v58+]cert9.db and possibly cert_override.txt : Stores all your security certificate settings and any SSL certificates you have imported into Firefox. If removed, the cert8.db, cert9.db file will be replaced.
search.json.mozlz4 : file stores the user-installed search engines that are available in the Firefox v47+
search.sqlite file and searchplugins folder store the search engines that are available in the Firefox Search bar before Firefox v47
Copy these files from the old to the new. You may get a message that the files already exist. Choose to over-write for each file.

Back up and restore information in Firefox profiles {web link}
I use a Legacy add-on that makes backups of my user profile, Just In Case.
Unfortunately, it is not compatible with the current Firefox.
Every now and then, open the profile folder and create a copy of the current profile as is to another location on your hard drive. This way you will have a backup.
If you do this each day, you will not lose much data. This should be done with Firefox Closed.
Note: In case you need to restore from these backups, you may need to overwrite old or corrupted files.
