If you are going to store your passwords, I strongly suggest using LastPass browser add-on. No browser has very high password encryption so if someone got access to your system, they could easily grab your passwords. LastPass uses military-grade encryption to keep your passwords safe and the great part is, it's free!
Check your settings and see if there's a setting that's been changed, like the other guys have said. If you're still having problems with it, shoot me a Direct Message and I'll walk you through it
