Re: How can I recover passwords in firefox 13.0.1, after an OS change [reinstalled windows 7] and the old programs are in a windows.old folder. Thanks in advance...
You want to copy your firefox profile across. If you have sync set up and running on another PC, that's the easiest way to copy things across to a new install ( see the article on adding a device to sync.
If not, you can copy the folder that contains your profile across. Have a look at the support article on profiles ; there's a section on how to copy without opening firefox, which should point you to the right directory to copy across.
