When it comes to security, Chrome has far better security than Firefox. Firefox is actually one of the least secure browsers.
Based on my own research, expert opinions, and personal opinion, I would respectfully disagree.
While Chrome is certainly not an insecure browser, Firefox simply trumps it, specifically in terms of privacy. Chrome does receive security and privacy update patches more frequently than any other browser I am aware of, however, Firefox is overall more secure and focused on user privacy. The differences between Firefox and Chrome in terms of anti-phishing and malware protection is more or less negligible. Nevertheless, it is no secret Chrome (and more specifically Google) are infamous for tracking and invasions of privacy and recently several U.S. states launched investigations into Google over privacy concerns [and antitrust violations]¹. Meanwhile, Firefox is (as far as I am aware) the only popular web browser which is open source, thus giving it's users a sense of security that no malicious practices are going on within the browser without their knowledge. Moreover, Firefox offers Content Blocking, allowing users to prevent websites from tracking them and simultaneously blocking popups, external links, and generally enhancing the privacy and experience of users. Out of my own testing and that of research, Chrome is significantly slower than Firefox. Before posting this message, I ran a quick test and Chrome took 5.95 seconds to load mc-market.org while Firefox took just 3.09 seconds. Lastly, Firefox offers a whole host of password and privacy features such as built-in Two Factor Authentication, statistics for which sites are having content tracking blocked, automatic breach alerts for your stored emails and passwords, as well as compatibility with iOS for fingerprint and FaceID password protection.
I will conclude by referencing and privacy ranking article made by ExpressVPN where out of the nine most popular browsers (IE, Edge, Opera, Chrome, Chromium, Apple Safari, Brave, Firefox, and Tor), Chrome ranked 6th receiving 9/15 stars while Firefox ranked 2nd with 13.5/15 [with Tor being ranked 1st]².
