hands down roboform. I have used several methods starting with spreadsheets and progressing through pass managers that require you to copy and paste the username and password into the page. Copying and pasting through the clipboard is a security problem since someone can write an application that monitors the clipboard and sends them that info.
Roboform doesn't use the clipboard and it recognizes the page you're on so all you have to do is click one button to enter the un, pwd. You can also select the login from a list and it will navigate to the page, enter your login info then submit the form!
You need it desperately.
