Well it works, but watch out: it's NOT open source! That should be made very clear on this add-ons-site.
I like to avoid closed source as much as possible, especially when it's about my security. Not only can we validate the code, but their is also no guarantee that LastPass' source will be sold to a not friendly third party. Also if LastPass goes out of business no-one can guarantee the safety of my online profile anymore.
Yes, I know; it's all about trust, but believe me: don't trust someone behind closed doors when it's about your security.
