Trying to transfer my FF profile from old computer to this one. Nothing in your help pages is working. The file is not corrupt. Any help will be appreciated.

Posted

I have done everything that is in the support answers, but to no avail. When I open FF in my jalopy (10 yr old computer), all my current bookmarks, and history for the past 5 years are still there. After copying the profile, and the entire Mozilla folder (separate attempts), and over-copying the folder in my new computer, there is no change; the files only go back to when I first installed FF on it. None of your support answers say anything about whether to copy the jalopy files into the local, or roaming folders, so I copied it into both. Still no difference.

In a related migration/replace problem, I cannot sync my new computer with the old, even though they're both in the same account name. The jalopy and new computer names are both recognized in the jalopy, but the new computer doesn't pick up the old computer name. This was the first thing I tried to reconcile the two machines. I am extremely frustrated, and at my wits end dealing with this problem. Any reasonable assistance and solutions are appreciated. Thank you.

P.S. If there is a response, will I receive an email or message on my FF account, or do I have to read through 800 instances to find the answer?

Can you more detail what you exactly did ?

If you restore a full profile folder then you need this profile registered in profiles.ini and show up in the Profile Manager.

If you copy files to an existing profile folder with Firefox closed then make sure to copy the files to the correct folder.

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.

oh, just zip the user profile folder in the old computer and unzip to the according location in the new computer. It always works and the most easy way if the versions of the firefox in old and new are compatible.

You need to copy the files to the AppData\Roaming location. You do not need the secondary "AppData\Local" location because only temp files are stored there.

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)

I've done this several times to no avail. I've tried all other things I found online. Also without success. Do you think uninstalling ff, then redownloading and reinstalling it might work? At any rate, I appreciate and thank you for your effort. (BTW, this isn't an 'old' profile. It's the same one I've got on the jalopy, just copied from one machine to the other yesterday, then again today (same account name.) The jalopy has at least a decade of history on it. This machine goes back to last month.) Again, thank you.

If you open the internal about:profiles page in Firefox on the new system, can you find a listing for your migrated profile and select it as the new default?
