see Preferences are not saved

thank you

Thanks, that worked. But now all my saved usernames and passwords are no longer automatically filled in like before. Instead now I must double click the username box to get the drop down menu of my saved username to show, then click it. How do I change it back?

See if you have selected Remember passwords for sites in Options window > Security panel > Passwords session.

see for more info : Options window - Security panel - Passwords

thanks again

I figured it out! I accidentally had it set to not remember any history as shown here:

I fixed it and now everything works fine. Thank you for responding!
