I had some issue with my Firefox (it crashes when i starts), so i format my laptop to factory setting and now i got new Firefox installed and left with this Old Firefox Data folder.

my question is :

Ii understand the profile in my Old Firefox Data contains my Bookmarks and information i previously had before i formatted, i just do not know how to apply this Old Firefox Data to my new Firefox to get what i need.

How do i use Old Firefox Data to restore all my bookmarks and information?

You can move some files from the "Old Firefox Data" folder to the current Firefox profile folder.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

It is best to only copy what you need and avoid copying the full profile content.
