I just went thru this with trying to get the passwords from a computer that the mother board broke.
Chrome pass worked for me on Opera
http://www.nirsoft.net/utils/chromepass.html
go to the advanced options
click the button " Load the passwords from another windows user or external drive"
in the line below type K:\users\admin where admin is the name of the user account. Mine looked like
E:\Users\ingen_000.
BAM! all 89 of my passwords were recovered and exported in html format for easy access.
Thanks every one for help on this!
