And I have a bunch of friends that say it's because it lacks the profile functionality and they can tolerate the speed. It's not the only issue Firefox has, but it's the highest impact, lowest effort one they have. Performance improvements are hard, PWA is hard to implement. Putting a better UI on existing functionality is simple by comparison. They could score an easy win here, but they choose not to.
