I don't understand this addon :( Puntuado con 1 de 5 estrellas

Sorry, but I don't understand how this addon works. I don't know if it's working or not. I expected that this addon will add automatically the "S" to the "http" but it won't. In fact, I must have to do it by myself, and then an error warnig appears in the screen when the SSL connection isn't done. I also expected that this addod will detect the Firefox warning when the SSL connection is refused and then get back from "https" to "htpp" automatically, but it won't again. None is automatically here. :(

Hi, pituso,
Thank you for taking the time to review my addon.
You are correct when you say it does nothing automatically. If you want to change the http to https and vice versa, you need to click the little "+S" or "-S" icon in the status bar. It's a simple widget that does exactly what I stated it would do, and nothing more (no warning detection or things like that).
I hope this cleared things up a little. :-)
