Possible Bug: When accessing passwordmaker through the Firefox toolbar icon, I found that the domain was not always getting automatically updated when I was on a new site. Instead, it was still on the domain where I had last used passwordmaker in this browser session. If I did not notice this, I might be using be using the domain from a previous site when making a password on a new site - big problem.
To avoid this problem, I have removed the toolbar icon and am instead accessing passwordmaker through rightclicking in the password input box.
