Firefox 57 was the first version of Firefox to use the Quantum engine, replacing the old Gecko engine with components written in Rust combined with C ++. The replacement took place slowly, starting last year, which Mozilla described as "replacing aircraft engines while still flying".

Firefox 57 will have a lot of Project Quantum code like Quantum Render - a new optimized pipeline for the GPU based on the Servo WebRender project, and Quantum DOM Scheduler - the technology that keeps tabs in the background without slowing down the tabs .
Mozilla said that these changes will significantly increase Firefox's speed, although it's really hard to say since which browser when launching the new version doesn't say so.
Besides the new engine, Firefox 57 also brings the new browser interface, a product of the Photon project, starting at the same time as the project Quantum. Photon UI brings browser UI, New Tab page and new dashboard.
Install Firefox Nightly to preview the new look of the browser
Firefox 57 also disables the search widget that often appears in the right corner, if you want you can turn it back from the control panel. New UI changes may also make users dislike because the add-on Classic Theme Restorer Firefox is no longer usable, meaning they cannot control the browser UI.
To preview the Firefox 57 interface, you can install Firefox Nightly (scroll down to download it). If you don't like it, you should find a different browser.
Besides big changes, there are some small changes such as turning on Tracking Protection at all times, security helps prevent malicious applications from monitoring users.
Mozilla Firefox 57 called Firefox Quantum will be released on November 14 next week.
