This is a major ripoff!!!
Why would I give anyone all my information???
A much more secure means is a password manager that will keep all data within your PC.

This review is for a previous version of the add-on (1.51.2). 

You do not understand how it works.

You're not giving LastPass your information, we bend over backwards to make this very clear. You're encrypting your sensitive data LOCALLY on YOUR COMPUTER, then sending LastPass that ENCRYPTED data. The data is encrypted with a key that LastPass does not have, so it's safe. The driver of your safety is simply picking a good password. https://lastpass.com/technology.php
