I removed my ssd from my Win 7 pro computer and inserted it into an external case. If I plug it into my new Win 10 computer, I can see all my Firefox files - including bookmarks folders - see attached. But the files are all in JSONLZ4 files. I'm now lost. Can anyone tell be how to load these onto my new Win 10 computer?

It looks like the Restore bookmarks from backup or move them to another computer page is what you are looking for. You need to copy the most recent backup file from your old drive and then open it in the Firefox bookmark manager.

Hope this helps.

Note that you can restore more personal data. See:

You can copy files like these with Firefox closed to the current profile folder to recover specific data.

  • 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
