Is it better to have Firefox remember passwords for sites or is it better to enter it manually each time? Which is more secure? My computer requires a log-on password and I also have a master Firefox password that must be entered every time. I still take this precaution even though I'm the only user at my house. But what if the computer is hacked? Is it less secure that you have had Firefox remember the passwords and user names? Also if someone stole the computer, can they remove the hard drive and access my data without my passwords?
