how do I install an older version of FF

Posted

I found the directory with all the older versions of FF. but how do I download an executable file? I did a recent new install of FF on a new HD and now my passwords are gone - despite restoring the backup files. the new FF I downloaded uses lockwise; while my older version did not. I am hoping if I download and reinstall a slightly older version of FF - where I can restore my passwords and history and bookmarks and it actually Works - then if I update FF - all my 'stuff' will carry with the newer version.

Unless you have another idea of how to get my old FF back! yes I made a backup of my old profile.

thanks

Both Lockwise and the legacy Password Manager use the same files for storing the passwords (logins.json and key4.db). This is only a new frontend to inspect and manage the logins and it shouldn't make a difference.


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

  • bookmarks and history: places.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 (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
    if you only have key3.db then make sure to remove an existing key4.db
  • cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
    if you only have cert8.db then make sure to remove an existing cert9.db
  • persdict.dat for words you added to the spelling 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)

You download the version that you want. Close Firefox. Then run the installer.

Note: Some versions of Quantum change how the data files are set up, so they are not backward compatible.
