I use mozilla and the save passwords feature. On the tripadvisor.com site, I have a saved password. Yet, mozilla won't auto-fill the password. Go to www.tripadvisor.com and try to sign in. If you don't have an account, don't worry, just click on sign-in and remember to turn on autocomplete on the form. Enter a username and password, when mozilla asks whether to save it or not, say yes. OK. close your browser, clear cookies, all of that and go back to tripadvisor.com and click on sign-in. The password won't be populated. Yet if you were to View Page Info -> Security, you'll see that passwords are stored. I can get the username and password from there and fill them in and that gets me logged in. What I'd like to know is this. How can I get mozilla to populate the passwords automatically; they are stored, mozilla has them, just won't fill them in.
