Refreshed Firefox and lost all bookmarks

Hi, I just refreshed Firefox on this site https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings because my browser was getting slower and recommended that to me with a little Pop-Up at the bottom of my screen. I first read through the whole page and it clearly says that I will not lose my booksmarks, but exactly that happened. I already read through most support articles, but they all mention a second profile in about:profiles but there is just one. The bookmark folder is empty in this profile. Does anyone know how I can get them back? Thanks

You can copy certain files with Firefox closed to the current profile folder to recover personal data. Note that best is to avoid copying a full profile folder.

  • bookmarks and history: places.sqlite
  • favicons: favicons.sqlite
  • bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
  • cookies.sqlite for the Cookies
  • formhistory.sqlite for saved autocomplete Form Data
  • logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
    if you only have key3.db then make sure to remove an existing key4.db
  • cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
    if you only have cert8.db then make sure to remove an existing cert9.db
  • persdict.dat for words you added to the spelling checker dictionary
  • permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
  • sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Do you have the Old Firefox data folder on your desktop?

Yes I do. There is another profile in there, which is probably my old one, right? Could you please tell me how I can add it or should I just cop everything from there into my new profile?
