Rated 5 out of 5 stars
It's just an annoyance for the lack of option to display the password upon typing. It is good for you to identify the typo in case your password is very complicated.
What I only want is an option to display the Master Password, but not all password fields. So, one password rules all without a great compromise in security in combination with Secure Login.
Why are there several strange 1-star reviews at the bottom? Do they know a "cancel" button is always with the master password prompt? As clicking cancel will not have any negative effect on the password protection mechanism, unless the password is filled in, no one can access the password database.
Also, please update this for the Firefox 3.5, so more people can benefit from this addon.
