Hi,

I don't know how but it seems I lost all my account related data. I connected my account to my new computer but I don't have anything: no history, no apps, no password. Is there anything i can do? I have the hard disk of the old computer, can I restore the data from it?

Thank you

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
