Just a small personal touch -- my coworker is constantly pushing me to use Chrome because it "just works", but I'm stubborn as hell. Used Firefox from early 2000s. Oh how I will love to twist his nerve even more once I will switch to Ladybird. Saying this because there has been more harder days to counter these pushes. And to be honest I think we are overthinking about how much this last 3-5 % actually matter for huge crowds.

I understand that your argument still stands in big picture, but in this big world there is plenty of room for Firefox and Ladybird and there is more than enough room to grow. Firefox mostly is being held back with their organization. I'm not convinced that it is technical problem.

But then again, I'm still believing that there will be a year of desktop Linux coming. Maybe even sooner than we expect.
