That was true several years ago, when Firefox was essentially the only player and optimization seemed a concept unheard of in web browsers. Then came Chrome, which in its earlier versions was really fast compared to Firefox, this paired with pervasive advertising by Google made many users jump ship to Chrome (including myself, for a brief while before caring about privacy became more important than speed). Years passed with Chrome totally deserving the prize for speed, although it was just like today a nightmare privacy-wise, but hey, it comes from the #1 targeted advertising company in the world, what should I expect? Fast forward a few years (iirc it was roughly in 2018) and Mozilla devs show they learned the lessons: the next Firefox release runs on par with Chrome, then following versions get some further improvements in speed too. So yeah, Chrome was indeed faster than Firefox, but that is a thing of the past. Speaking personally here, but I value privacy a lot more than bells and whistles or speed, so Chrome is a no-no here regardless of its performance.
