Both teams were working on browsers, but in different decades. Chrome benefitted from employees wanting work/life balance, a company that had many moon shot projects, and former webdevs who made incremental releases of desktop software possible. This removed a lot of pressure.
Chrome was delivered without any sprints at all. The team came in at 9 and left at 5 (figuratively, people actually kept their own ~8h schedules) every workday for a couple years like clockwork. No drama. No broken marriages, no broken families.
