Firefox for Mac

 -  100% Safe  -  Freeware

What's new in this version:

- In October of last year we announced Project Quantum, our effort to create a next-generation engine. Firefox 57 includes many aspects of this project, so we’re calling this release Firefox Quantum.
- Firefox Quantum is roughly 2X faster than Firefox 49 on the Speedometer 2.0 benchmark, thanks to its new CSS engine, its “just right” multi-process architecture, the way it prioritizes your active tab, and much more. Firefox Quantum also includes a visual refresh – Photon – that looks and feels right at home with modern operating systems. To learn more about Firefox Quantum, visit the Mozilla Blog.

New:
- Firefox is getting a major Visual Redesign (Photon project) activated on the Nightly channel and which will ship with Firefox 57 on the release channel.
- Allow users to manage the site data
- Added support for Date/Time input
- Accessibility indicator will now appear in the title bar of the window when Accessibility services are enabled

Changed:
- Support more strict sandboxing protection (level 3) on Linux
- The browser's "autoscrolling" feature now uses asynchronous scrolling, similar to other input methods like mousewheel, providing a smoother scrolling experience.
- Middle mouse paste in the content area on Unix systems no longer navigates to URLs by default

Developer:
- The "Share" button was removed. If you relied on this feature, you can install the Share Backported extension instead
