Meet Firefox Quantum, Mozilla's most compelling answer to Chrome yet


Its memory tests showed a noticeable decrease in memory usage compared to Google Chrome on Windows 10 and Linux; on macOS 10.12, memory usage was pretty much the same.

The browser market may about to become a lot more competitive. Right now, Chrome boasts a 54.57% market share, while Firefox is languishing at 6.08%. This is in the form of Project Quantum, Mozilla has changed the soul of their open-source web browser.

Mozilla isn't pulling its PR punches.

"Firefox Quantum is over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology stolen from our advanced research group, and graced with a attractive new look created to get out of the way and let you do what you do best". Firefox Quantum sports a brand new interface called Photon that Mozilla has created to cement the impression of a more responsive browser.

According to a blog post, Mozilla's year-long overhaul changed or added over 11 million lines of code, though it's not clear if "changed" includes "deleted" (presumably it does).

Since then, they reportedly dug the tunnel which stretched to 25-feet, to reach the locker room of the Bank of Baroda branch. Thieves dug about 30 feet long, an underground tunnel which leads to the locker room of the bank of Baroda.

Firefox Quantum is also said to operate at double the speed of a slightly older version of Firefox from earlier this year. All the mobile browsers are getting is an update to their UI. I have never liked Microsoft's decision to embrace a gradient-free future; it makes it harder to navigate options, not easier. Firefox refused to differentiate properly between two different versions of the browser, even when we consulted guides on dual-browser setup.

Those who already use Firefox should receive an automatic upgrade to Quantum after restarting their browser. You can also choose between three other, more artistic themes, and can mix and match densities and themes. We took a closer look at Quantum back when Firefox 57 hit the developer channel in September, but the short version is, Mozilla is rebuilding core parts of the browser, such as how it handles CSS stylesheets, how it draws pages on-screen, and how it uses the GPU.

Our own initial tests on Quantum confirm that it feels snappier, though perhaps not as much as we'd have seen under different circumstances.

What's your take on "new Firefox"?

The only down side - or potential down side, if you consider it as such - is the addition of "Recommendations" in the Firefox startup page.
