This means that unlike previous versions, Firefox Quantum can now take advantage of all CPU cores, especially with the CSS engine that plays a major role in fast web rendering. If ideal, this also means Firefox will consume less memory (less than Chrome).
The group also launched a new interface for this release. For example, the rounded tab is gone. The new interface focuses on simplicity and speed. As in previous versions, users can still edit the interface to their liking but still look good on a high-resolution screen and work better on a touchscreen laptop.
Mozilla continues to support the integration of Pocket even though not everyone likes this. Firefox Quantum also has an integrated screen capture tool and a centralized reading mode.
Quanttum is expected by many very attractive features
If you have used the Nightly version you will see the difference between the new version and the old Firefox is the night mode.

For example, why does LastPass not release a compatible version of Firefox 57 Beta plug-in .
Is Firefox Quantum better than Chrome? No, but they are equal and the choice is based on personal assessment only. You may like a browser of an independent party, regardless of Google.
Firefox 57 Stable will be released on November 14. Until then, you can try out new features on Beta and Developer.
