Installed ff on new C drive and trying to import my profile from replaced, working drive. Got as far as pasting previous folder into new one and see new files were added. Both drives W10. But clicking bookmarks and passwords gets "nothing saved." Cannot decipher folder contents, & without details it's a dead end.

Likewise there is a page here on "importing bookmarks from another browser", with a link. It opens to window where you can look for the file. Same problem, not knowing where bookmarks are. Is there a place to find details on what profile folders and files store. Or am I missing something else? Thanks for assist. -- PS Images could be added if any purpose.
