The new Firefox for Mac is fast, responsive, and puts your privacy first. If you want a secure, easy-to-use browser, now is the time to download and switch.
New look: Firefox 57 uses the new Photon interface. The new UI turns the older rounded tab corners into rectangles and reworks the address bar/toolbar area. Pocket is also integrated into the browser, letting you save pages to view later.
Quick and responsive: In our informal tests -- launching with the same set of tabs -- Firefox 57 opens faster than Chrome 62. Firefox 57 uses a bit less memory than Chrome 62 on the same set of tabs. And pages that Chrome struggles with (like ESPN's fantasy football pages), Firefox handles smoothly. ZDNet conducted more formal tests on the two browsers and found Firefox more than holds its own with Chrome on speed tests.
Keeping your browsing private: Through Firefox's privacy settings, you can set how and when the browser blocks trackers and turn on (and off) tracking for individual sites. You can also control how Firefox handles cookies (accept them all, exclude third-party cookies, exclude them all, or accept cookies from specific websites you create exceptions for). You can also open a Private Browsing window to block all trackers and erase your browsing history when you close the window.
Extensions and themes: Firefox add-ons can take small browser tasks and change the look of your browser. You can block trackers, keep lists, watch for online deals, and more. If you already use extensions, Firefox 57 moves to a new add-on model that breaks legacy extensions. The good news: many of the popular extensions have been rewritten to work with Firefox 57.
Manage passwords: Through privacy preferences, you can have Firefox remember your log-ins and passwords for websites. You can also view your saved log-ins to see your username and password for each site. If you share a computer, you have the option of using a master password to access your log-ins and passwords. If you forget your master password, you can reset it, but the process removes all your saved usernames and passwords.
Sync Firefox across platforms: By setting up a Firefox account, you can sync account information -- including bookmarks, passwords, and extensions -- across desktop and mobile platforms.
Some extensions missing with update: With the move to a new extensions model, some older and popular extensions didn't make the move over -- yet -- to Firefox 57.
The Quantum update to Firefox closes the gap between Mozilla's browser and Chrome -- and in some areas moves it ahead. Firefox is a pleasure to use, and if you are looking for an alternative to Chrome, download Firefox for Mac for free.
