Mozilla has launched the beta and developer versions of Firefox Quantum, the next edition of the Firefox web browser featuring a new engine that’s built for speed.

Quantum, also known as Firefox 57, is a serious improvement from the previous version (Firefox 52) as it makes the most out of multi-core processors found on modern PC and mobile hardware.

Firefox Quantum also prioritises the tab you’re currently using – it downloads and runs before the other tabs not in use, cutting RAM usage by around 30 per cent.

The company has released a video that pits Firefox Quantum against Google Chrome running various popular websites. From the looks of it, Quantum is seriously giving Chrome a run for its money:

I have tested both Chrome and Firefox Quantum using a free online browser speed test. The results clearly shows that Firefox Quantum beats Chrome on calculation, storing and rendering areas with an overall score of 743.47.

If you’re a heavy Firefox user, you’ll be upgraded to Quantum automatically on November 14. You can download the beta for desktop, Android and iOS.
