Lots of things. It's just way far behind on standards. Chromium based browser is the way now until a whole new engine comes along imo. There's nothing promising even out there rn. All the chromium based browsers that are good in terms of performance have a bunch of bloat or personalization settings you can't change that make them suck. Ungoogled chromium is the cleanest base state of chromium so I use that now. I've used almost all desktop browsers now and most mobile ones. Ama
