Lockbox Extension is a free extension developed for the Firefox web browser from Mozilla. Designed to improve upon Firefox’s existing built-in password management, Lockbox Extension looks to streamline the process. Currently still in the development stages, it’s rapidly changing and not guaranteed to be the same extension it will be when released to the general public officially. Still, users can install and run Lockbox Extension, and for those who are familiar with open source code, they can even contribute to the project.
