We're super excited to get Firefox Quantum to our beta users and hope you'll give it a try.

The speed tweaks have appeared in Firefox over the past months and with Firefox Quantum, also known as Firefox version 57, are set to be joined by the Photon user interface, which designers built based on research into when users perceived browser rendering time issues.

Firefox is the latest popular web browser to move against or away from Flash and that's happening with version 56.

We've shipped a lot already, but we've been planning for many more projects to come together in Firefox Quantum. But those were just the tip of the iceberg.

"Firefox Quantum is about 2X faster than Firefox was a year ago", he said, citing the Speedometer 2.0 benchmark, and comparing Quantum to March's Firefox 52. In the video above, you can see Firefox Quantum appears to be faster than Chrome on various websites. There's also a Developer Edition available. For example, we've transformed Firefox to run using multiple processes, striking the "just right" balance between speed and memory usage.
