I'm buying a new computer and I'm wondering is there a method/procedure that I can use to transfer the entire FF browser including settings, extensions, bookmarks, and passwords without having to reinstall all those items individually? I know I can save and import bookmarks but what about everything else? I look forward to anyone comments. Thanks

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

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


  • 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 (encrypted logins;32+) and key4.db (decryption key;58+) for Passwords saved in the Password Manager
    key3.db support ended in 73+; to use key3.db in 58-72, make sure to remove key4.db
  • cert9.db (58+) for (intermediate) certificates stored in the Certificate Manager
  • persdict.dat for words added to the spell 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)

Thank you for you reply. Seems a bit complicated to me. What i thought about doing was to export my bookmarks to a USB flash drive and export my logins/passwords to my flash drive and then import them into FF on my new computer. Any thoughts about this method? Thanks

For the bookmarks you can use JSON backup (restoring replaces all current bookmarks) or an HTML backup (importing merges bookmarks).

For exporting the logins, see:

You need to enable import CSV in the Password Manager (about:logins) via the about:config page as this menu item is currently hidden for performance reasons.

I'm going to use the sync method to transfer everything to my new computer-passwords, logins, bookmarks, extensions etc. In order for this work properly I have the following question:

How long should sync be enabled on the old computer before transfer and how long should it be enabled on the new computer to be sure everything is transferred? Thanks
