I recently "downgraded" from macOS Ventura back to macOS Monterey on my 2019 Macbook Pro. Is there a way to migrate all the Firefox bookmarks and login/password info that I had prior to the downgrade? I made a complete backup of the computer prior to the downgrade, but I can't find any folders with this info on the backup, just the Firefox application. I didn't make the .html or .csv files of the bookmarks or login info prior to the downgrade--didn't think it would require such steps to migrate the old info.

The Firefox profile folder with the random name (default-release.xxxxxxxx) is normally in a hidden location in ~/Library.

Primary location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • ~/Library/Application Support/Firefox/Profiles/
