yahoo has a sign in seal, word or picture, for security. i set up a picture seal, save it in yahoo, it works as i sign in and out of yahoo but if i close my browser and go back to yahoo after i restart my browser there is no sign in seal. also on the weather channel website where you can have 3 saved locations up in the right corner, i save them,leave the website and go back, no problem, close firefox, restart firefox and the locations are not saved on the weather website. same with my banking security questions, i have to answer them every time i go to the website even though i checked the box to save them on this computer. this is a brand new computer with windows 7. been using windows xp on old computer with firefox for years with no problems.
