I'm on firefox 49. This started happening in a previous version, but when I went to see what version i had installed, firefox updated. I have a couple of username/passwords saved in the builtin password keeper in firefox. I have the "remember logins for sites" option unchecked. Until recently, i could go to a website that has a stored username/password and firefox would fill in the info. Now, nothing gets filled in. I can right-click in the username field and select "fill login" and my username and password will be filled in. If I enable "remember logins for sites", firefox will automatically fill in the username/password. Either there was a bug introduced that prevents saved username/passwords from being auto-filled when the save option is unchecked or the default behavior of that code has been changed. Can someone tell me which it is?

Thanks.
