It's not generating a strong password. Noté 3 sur 5 étoiles

Good thing about this addon is doesn't require to restart the firefox.
But it's not genrating completely secured password as it doesn't have option to choose special characters.

If u really want a strong password should be 8 or more characters and should have Capitals, Smalls, Numeric and atleast 1 special character. So it's not following the standards. There is no provision to choose in the options to include a special character.
Only Average. U can still go ahead & use it if security is not main crieteria to generate password.

useful and simple Noté 5 sur 5 étoiles

nice addon, very nice interface we can create password just a click.
