Do this just once, it might be a time consuming task but it will solve the problem forever. Download an app called Lastpass and it will the install extension for firefox, IE and Chrome. Add all your passwords to Lastpass and thats it. You will have all your passwords synced to all your browsers plus backed up to their servers all for free.
(See if you can directly import that CSV, HTML file explained above into Lastpass otherwise doing it manually might be a n awfully long task but its totally worth it)
