in window firefox there is a readily accessed configuration directory with files where bookmarks are stored with json extsentions. How can I access the analogous files in ubuntu linux and install my windows json files.

Chosen solution

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.


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

  • bookmarks and history: places.sqlite
  • bookmark backups: compressed .jsonlz4 backups in the bookmarkbackups folder
  • cookies.sqlite for the cookies
  • formhistory.sqlite for saved form data
  • logins.json and key3.db (decryption key) for Passwords saved in the Password Manager
  • cert8.db and possibly cert_override.txt for (intermediate) certificates stored in the Certificate Manager
  • persdict.dat for words you added to the spelling checker dictionary
  • permissions.sqlite for Permissions and possibly content-prefs.sqlite for other Site Preferences
  • sessionstore.js for open tabs and pinned tabs
