In the nine years that it’s been around, Google Chrome’s speed and simplicity convinced most of us to make the switch from whatever browser we were using before (though not everyone is a Chrome fan).

With a major overhaul and some serious streamlining, Firefox is hoping to claw back some of that market share.

A newly updated version of Mozilla’s browser, with the fancy name Quantum—or Firefox 57—launches today, and at top level, it promises browsing speed that’s twice as fast, all while using significantly less memory than Google Chrome.

Firefox Quantum feels fast: Pages generally load up in a snap, even when you’ve got a bunch of tabs open and are running interactive online apps like maps and email clients.

From page load times to the responsiveness you see when you type out a URL in the address bar, the speed increases are apparent.

That’s thanks to an all-new web rendering engine, also called Quantum, replacing the Gecko engine that previous versions of Firefox ran on.
