I have installed new update 56.0.1 and since update all my browser history and passwords have gone. I have tried copying and pasting into profile but old data profile will not paste into new data profile. I have spent 5 hours trying to retrieve my information with no success. I am wondering if firefox has set up a new account because it asked me to sign in which I could not remember my log in details so asked for new password. Since new password has been entered then no past information.

I have the old data file on my desktop but cannot paste. When I right click to paste then drop down menu shows no paste word.

Please help I have used firefox for years and years and cannot believe this has happened

If you are talking about sync;

Resetting the sync password, or changing its e-mail, will remove all data from the servers.

This is a security feature. https://support.mozilla.org/en-US/kb/ive-lost-my-firefox-sync-account-information

You can copy individual files like these 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

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.
