I'm sure you can just Google what the benefit of using Firefox is. When "privacy" is talked about in terms of web browsers and apps, it's mainly about blocking trackers. Ad companies inject trackers into websites and apps, which collect your data. Google has their own ad company, and by using Chrome, you're supplying them with personal information without them even having to pay. Firefox doesn't sell your information. They also have many extensions available that will block any data collecting attempts from websites.
Duck Duck Go is even more secure. The whole point of their browser is for user privacy. Their app even blocks other apps from tracking you. You'd be amazed by the data collected by apps. My fucking shopping list app has trackers from multiple companies.
