Does firefox actually encrypt them and require a master password to open them up? Times have clearly moved on... Back in the day, it (or whichever browser I was using in 2009) used to just autofill the passwords for the site, I assumed they were just encoded somewhere, not encrypted.

I use a mixture of things I've been meaning to consolidate for a while... all of which are a big list of unique (obviously) passwords stored somewhere encrypted by a long password.
