Henry,
Thank you for the response. I use Firefox browser. I attempted to follow your answer and was unable to save the setting. I use Firefox browser and my settings do Delete cookies upon closing. I am able to go to Privacy settings and add exceptions for cookies allowed. Would it work to add an url to exceptions? What url address would I add?
Thank you!
