    • Mozilla announced Firefox Quantum
    • It comes with major UI overhaul
    • It is claimed to be much faster

In what could be a major overhaul of Firefox browser since its debut, Mozilla has officially introduced the new Firefox Quantum. Based on Project Quantum that was first revealed by Mozilla’s David Bryant, the new Firefox browser is claimed to be over twice as fast as it was earlier. In a recent blog post, Mozilla made an announcement and explained its working, features and everything users would want to know.

With the new update, Mozilla’s primary focus remains on speed and user interface dubbed Photon UI. Mozilla also said in the blog post that Google will be the default search engine with Firefox Quantum in the United States and Canada. “With more than 60 search providers pre-installed across more than 90 languages, Firefox has more choice in search providers than any other browser,” the company added.


Firefox Quantum is available for download across desktop (Windows/Mac/Linux), Android and iOS. We installed the browser on Windows 10 to verify speed performance claim made by Mozilla, in addition to learning more about its user interface. If you are a Windows user, Go to, download the installer and hit install. Smartphone users can download Firefox Quantum from their respective app stores.

The first thing we noticed is the UI overhaul. It looks modern now. Since Mozilla urged users to try working with multiple tabs opened at the same time, we decided to go for it. We opened over 15 tabs at the same time and faced no performance slowdown while switching between them, unlike Google Chrome.

Then we opened over 20 tabs in Firefox. We opened the same number of tabs in Google Chrome as well. Unlike Firefox, Google Chrome ended up consuming more system resources, which eventually led to performance/productivity slowdown. See the screenshot below:


Although Mozilla’s claim appears somewhat authentic with regards to Firefox Quantum, we’ll put it through our in-depth tests over the course of next few days and share our learning with you.
