No. Firefox has been dying for, what, a decade now (losing market share since 2013)? The only people using Firefox are the people who care about Firefox as a product and a competitor, which is (in the grand scheme of things), almost nobody. Everybody else left, often with decent enough reason. Google recommended Chrome, Chrome was faster for a long time, Firefox stagnated and put ads and sponsorships everywhere, and wasn't better in almost any respect for a normal user than Chrome.
