Mozilla today launched its new and updated Firefox Quantum web browser. Firefox Quantum is available for mobile platforms iOS and Android, and also on Windows, Mac and Linux. Along with the new layout and features, Firefox Quantum is being portrayed as really fast by Mozilla. Mozilla says that it is twice as fast as Firefox from six months ago.
Firefox Quantum offers a minimal design as compared to the previous version. The search engine toolbar stays at top with most frequent sites browsed arranged below. There’s also a ‘Highlight’ tab below which will show related articles, photos and videos of the most browsed content on Firefox Quantum. Mozilla has added Pocket as a built-in feature on the toolbar of Firefox Quantum. There’s also a Pocket library on the browser’s library from where you can access all the saved files. Additionally, the new browser library also has browsing history, bookmarks, and synced tabs all in one place.
Firefox Quantum also comes with a built-in screenshot tool. This eliminates the need to download any other third-party app to take screenshots. You can choose to capture a screenshot of the entire page or edit out only the portion needed. Screenshots will be saved to the web so you can share it further on other platforms. 
The address bar on Firefox Quantum is said to be the browser’s most powerful tool according to Mozilla. It also says that Firefox Quantum consumes 30 percent less memory than its arch rival, Google Chrome. Firefox Quantum also comes customizing tools like rearranging the toolbar by dragging and dropping. The browser also comes with themes you can choose from. You can sync your data on Firefox Quantum on different devices. 
A rather interesting bit in the launch of Firefox Quantum is the decision to use Google as the default search engine. After the completion of Mozilla and Yahoo‘s five-year contract, Mozilla didn’t renew and instead signed a deal with Google for its search engine. Prior to Yahoo, Google had been Firefox’s default search engine for 10 years. Mozilla terms this change as their experiment with different search engines for its users.
