Yes I'm also worried, on two fronts. The first being the 'top browsers' are just Chrome based anyway, creating a "works in Chrome only" scenario from decades ago. Which further fuels FF's decline. The second being the case of defaults, by which I mean the default browser that comes with phones and desktops (Chrome and Safari and Edge), which in turn promote the lack of openness of the web by being tied to the OS and again recreating/forcing the same scenarios from decades ago. The only difference this time is that there's nobody keeping these companies in check.
