Simple and works Rated 4 out of 5 stars

I've been using this plugin since 2007 - and it works perfectly.

I normally use the enter masterpassword +F2 function as the password visually gets 2 char longer

Tip for Beta users;

bypass the security check by adding the preference extensions.checkUpdateSecurity and setting it to false (though not recommended for casual users).

type about:config in the address bar and press Enter
1. Right-click -> New -> Boolean
2. Name: extensions.checkUpdateSecurity
3. Value: false '

Restart browser and install plugin
