Can Firefox be the culprit in my not receiving emails from certain senders? Microsoft Outlook 365, which I use within Firefox, doesn't show that the emails of concern are blocked. How do I determine if Firefox is the problem and how do I fix it?

Firefox is just a browser you need to check with your email provider about your email issues.
