@kev Do note that you were NOT allowed to choose Firefox; you chose a skin over Apple's Safari engine. When web tech moves forward, you wait to see if/when you can have it.
@alphazino is right, app developers can only use WebKit to render web pages. Everything else is just a skin around it. iOS 14 now allows you to chose the default app for web browsing. Before that you could use them but every link from any other app would still end up opening Safari. Now it opens your default app.
