Mozilla is announcing that the latest version of its Firefox browser, Firefox 57, is just too good for just another numbered release. The improvements under the hood are so great, they say, and the performance improvements over previous Firefox releases are so grand, that only one name would have been enough to convey this message. That’s why the latest Firefox release has been christened “Firefox Quantum“.
Mozilla are saying their new Firefox Quantum browser delivers 2x the score in Speedometer as their previous Firefox 56. The new, refined browser didn’t appear overnight, though; it’s seen numerous improvements under the hood through the application of the Goldilocks principle to browser design, straddling an approach between increased performance and acceptable memory usage. Multi-process and optimized memory footprint are part of the secret sauce, but a new, super-charged CSS engine written in Rust goes a long way. Prioritization of the open tab also helps this increased speed, while (Mozilla says) reducing memory utilization by 30% when compared to Chrome.
