We are a real and unique browser. Not a Safari skin.<p>There is no such thing as a Safari skin. Instead we use a low level component called the WKWebView, which is a bare-bones minimal API to &#x27;show web pages&#x27;. On top of that we have built a browser.<p>This is exactly what Apple has done with Safari.<p>The only common component between Firefox and Safari is the WKWebView. Everything on top of that, like the UI, bookmark management, history, sync is unique and implement in different ways by each browser.<p>Regarding JIT .. the WKWebView exposes the same fast JIT as Safari uses. Run a benchmark. We are as fast as Safari or any other app that uses the WKWebView underneath.
