Can't remove email addresses from Facebook login page, please help...?

[Gwendolyn L]

More than one person in my family uses facebook and sometimes family friends log on when they're staying with us to check their pages. This morning I realized that when I tried to use the arrow down and click the delete button, the email addresses were highlighted in grey and I couldn't remove them. The computer is only about a month old. It's an HP Envy, the system is Windows 8, and the browser I'm experiencing this issue on is Google Chrome. After I found where to uninstall, I tried uninstalling and reinstalling Chrome. Can anyone help explain what caused this and how to correct it? I had just updated Google Chrome prior to it occurring but I'm guessing that's not the cause as Google Chrome was uninstalled and reinstalled. This is just an annoyance because now I have several email addresses that start with the same letter of my facebook login email and instead of deleting the email addresses like I usually would, I have to either type more of the letters of mine out or scroll. Oh, I also have Webroot. I'm not sure what is to blame so trying to give as much info as I can. Thank you.
I tried uninstalling and reinstalling Chrome. I just tried clearing the cache too. That removed the email addresses, but as a test I logged out of Facebook and started to type my email address in, and sure enough it's there showing up and it's highlighted in grey. So while I got rid of the other emails, I know they'll just end up staying as my family members use Chrome to login to Facebook and any future guests. I just don't understand why I used to be able to arrow down and press delete and remove emails and they wouldn't reappear, nor were they highlighted grey, and now I can't. The only things that I did was I clicked the 3 lines on the upper right corner to update Google Chrome, and I updated Flash player.
