Hi Oryduck, which password is it asking for? In Firefox, you can set a Master Password to protect passwords you save in the browser. Firefox will ask for the Master Password the first time you connect with a site where Firefox would normally fill in that saved password for you. At startup, this could happen if you saved the password for your home page, or if one of your add-ons is using a saved password, or if Firefox is connecting with a service in the background using a saved password. Does it seem likely to be one of those things?
