A new CSS engine called Stylo. This lower memory footprint is most noticeable when opening multiple tabs (which all of us frequently do), as users won't see a drag on performance or crippling memory and CPU usage that can often cripple Chrome.
This week, Mozilla finally began rolling out its "Quantum Browser" update for Firefox. Thanks to the new (and overdue) Mozilla-made Multi-Account Container extension, you won't have to worry about remembering which account you're logged into. In fact, any product with the Firefox name will adopt it.
Firefox Quantum is capable of 66 runs per minute, that's twice as fast as its previous version, according to Speedometer, a browser benchmark that measures the responsiveness of web applications.
Firefox Quantum is now available on Windows, Mac and Linux, with iOS and Android versions set to arrive in the future. The tab a user is on gets prioritized over the rest of the tabs, which the company says consequently makes better use of one's system resources.
Beyond that, there are also three variations on the default theme, depending on whether you prefer the inactive tab to be the same color as the titlebar - in the default setting -, a more muted shade of grey, or dark grey, with the last one being particularly suited for work at night.
The Photon UI has also been streamlined compared to previous versions of Firefox, and is created to provide smooth and fast performance when browsing your favorite websites. As part of our focus on user experience and performance in Firefox Quantum, Google will also become our new default search provider in the United States, Canada, Hong Kong and Taiwan.
"To create Photon, our user research team studied how people browsed the web", wrote Mozilla's Mark Mayo. A Library button gives you access to your saved content such as bookmarks, your Pocket reading list and screenshots, making extensions for these services obsolete.
