How do I temporily open up more cookies?

Hello, In firefox, it allows First party cookies but blocks third party cookies, however ''for this specific website you are talking about'', enabling third party cookies is required. First, find the shield icon on that website, then click off for enhanced tracking protection (this allows the third party cookies for payment software) If you want to allow it for sessions at a time, right click the page, click View Page Info from the context menu, then click the Permissions tab at the top, after that, scroll down until you find the row labeled Set Cookies then uncheck the box that says "Use Default".Select the Allow (or Allow for Session).
