Unfortunately, this doesn't work on https://www.hightail.com.
Firefox itself (via a cookie) remembers username field, but not the password field. Even if I delete username field, no amount of click-clicking on it brings a drop down menu to fill the username (and/or password) with this add-on.

This review is for a previous version of the add-on (2.7.3.1-signed). 

To be exact, Firefox doesn't work with some sites. The behavior in question is not in the scope of SPE's responsibility. However, for convenience, I have documented this very frequently reported issue in the FAQ at the support site (link next to the "About this Add-on" section for this add-on). The FAQ is at https://groups.google.com/forum/#!topic/ddawson-addonssupport/dT1k0dKIJeo

In short, SPE is not a password manager. It works with the existing password manager; if a site breaks that (and many do), SPE will not solve it for you, nor is it intended to. Please read the FAQ for more details.
