This software requires Firefox 0.9 - 0.9+ and allows users to set a password within extension options. Once set, users can unlock all options by entering the password in Tools -> Enter Password after restarting Firefox.
After restarting, I found that all of the options within the extension were now locked with the password I had set. To access them, I simply had to go to the "Tools" menu, then select "Enter Password", and input my password when prompted.
Overall, I found this extension to be a useful tool for enhancing the security of my browsing experience. Just keep in mind that it requires at least Firefox 0.9 to function properly.
