2nd on Roboform
 

I have used Roboform since day one as well.
There are several advantages over letting your browser or email client handle your logins and passwords.
1) Security..is far better than with a browser which can be easily hacked.
2) Portability...Roboform will attach itself to most browsers and many login pages, like your bank or credit card accounts so you only need your information on one platform.
3) Profiles..you can make up various profiles that make filling out forms and applications like your shipping address for example an automatic process.
4) RF will also work cross platform on your phone as well.
Costs a few bucks but well worth it!
