People use different sites, so I believe it, especially "local" ones of zero interest to people in other countries.
That said, I've not used chrome on personal machines as a default browser for many years, and at work I also avoid it.
I don't remember when I last stumbled over a page that didn't work in Firefox... which then worked in any other Browser and was not broken per se. Or they didn't work with Firefox + UBlock Origin, which is fair as Chrome just blocks less.
I don't have any issues with firefox, and I seriously smell astroturf, when day after day Firefox gets bashed.
