I had a list of Add-ons on my Firefox running on XP. There were issues with the XP system that forced me to wipe the Hard drive and do a clean install of XP. Now that it is fully running again, I have installed Firefox. PROBLEM... I do not remember all the Add-ons and there settings. I did backup my previous system including c:\program files on another hard drive.

1) Can you point to where the Firefox info is stored? 2) Is there a way to copy the old file or can you read it and supply the Add-on names?

Thanks.

Firefox doesn't store personal data in the Firefox program folder location, but uses a folder in %AppData%.

You would need the extensions.json file to see what add-ons you previously had.

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

  • bookmarks and history: places.sqlite
  • bookmark backups: JSON backups in the bookmarkbackups folder
  • SQLite files like cookies.sqlite (cookies) and formhistory.sqlite (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 and tab groups

When you wiped the disk, did you save the old information?

yes, As I stated in my question, the files are on another hard drive - - I just do not know which files to look for.
