firefox 57 will not save my cookie preferences

Are you sure your Bitdefender isn't clearing the cookies? If FF isn't set to clear it then it would mean something else is doing it.

Do you mean the cookie settings in the Options or is this about exceptions or something different?

To see all History and Cookie settings, choose:

• Options/Preferences -> Privacy & Security -> Firefox will: "Use custom settings for history"

Thanks for the feedback.

I am checking both Bitdefender and my Firefox options. Testing now and will get back tomorrow
