2x faster

Powered by a new, cutting-edge engine, Firefox has doubled its speed from last year. Because the Internet waits for no one.

Lean, mean speed machine

Firefox Quantum’s new engine uses 30% less memory than Chrome, so other programs won’t slow down during browsing. Now that’s a win-win.

Beautiful, intelligent design

Hello, gorgeous! Firefox’s sleek, new look comes loaded with intuitive features like in-browser screenshots and more.

New Tab

Search across multiple sites, view your top pages and discover new content.

Powerful privacy

You’re in control of your online information. Use Firefox Private Browsing to block ads with trackers for extra peace of mind… and pages that load up to 44% faster.

Browse for good

Firefox is backed by the non-profit Mozilla, who keeps the Internet healthier through programs that support tech education for girls, create trust around factual news, bring civility to the comments section and more.

Shape Up Your Floats

CSS Shapes lets a floated element sculpt the flow of content around it beyond the classic rectangular bounding box we’ve been constrained to. For instance, in the above screenshot and linked demo, the text is wrapping to the shape of the grapes vs the image’s border. There are properties for basic shapes all the way up to complex polygons. There are of course great docs on all of this, but Firefox 62 also includes new tooling to both inspect and visually manipulate CSS Shapes values.

You can learn more in Josh Marinacci’s post on the new CSS Shapes tooling from yesterday.

Variable Fonts Are Here

No punny title, I’m just excited! OpenType Font Variations allow a single font file to contain multiple instances of the same font, encoding the differences between instances. In addition to being in one file, font creators can expose any number of variation axes that give developers fine-grained control on how a font is rendered. These can be standard variations like font weight (font weight 536 looks right? no problem!) or things that were never previously available via CSS (x-height! serif-size!). In addition to the candy-store possibilities for typography nerds, being able to serve a single file with multiple variants is a major page weight savings. Dan Callahan goes much deeper on the grooviness to be found and how Firefox makes it easy to tweak these new custom values.

Devtools Commands

The Developer Toolbar was an alternate command repl input in the Firefox Developer tools, apart from the Web Console. I say “was” because as of Firefox 62, it has been removed. It was always a bit hard to find and not as well-advertised as it could be, but did encapsulate some powerful commands. Most of these commands have been progressively migrated elsewhere in the devtools, so we’ve removed the toolbar altogether.

One of the last commands to be migrated is screenshot, which is a power-user version of the “take a screenshot” button available in the devtools UI. The screenshot command is now available as :screenshot in the Web Console. For example, have you ever needed a high-res screenshot of a page for print? You can specify a higher pixel density for a screenshot via the command: :screenshot --dpr 4

There are a bunch of other options as well, such as specifying output filenames, capture delays, and selector-cropped screenshots. Eric Meyer wrote a great primer on the power of :screenshot on his blog, and it will change your page capture game.

What's New:

Say hello to a fresh new Firefox, designed to get you where you want to go even faster. We’ve redesigned and modernized the core experience to be cleaner, more inviting, and easier to use.

Beginning in 89, you’ll notice a number of changes, including:

  • Simplified browser chrome and toolbar: Less frequently used items removed to focus on the most important navigation items.
  • Clear, streamlined menus: Re-organized and prioritized menu content according to usage. Updated labels and removed iconography.
  • Updated prompts: Infobars, panels, and modals have a cleaner design and clearer language.
  • Inspired tab design: Floating tabs neatly contain information and surface cues when you need them, like visual indicators for audio controls. The rounded design of the active tab supports focus and signals the ability to easily move the tab as needed.
  • Fewer interruptions: Reduced number of alerts and messages, so you can browse with fewer distractions.
  • Cohesive, calmer visuals: Lighter iconography, a refined color palette, and more consistent styling throughout.

This release also includes enhancements to our privacy offerings:

We’ve enhanced the privacy of the Firefox Browser’s Private Browsing mode with Total Cookie Protection, which confines cookies to the site where they were created, preventing companies from using cookies to track your browsing across sites. This feature was originally launched in Firefox’s ETP Strict mode.

  • For macOS users, we're introducing the elastic overscroll effect known from many other applications. A gentle bouncing animation will indicate that you reached the end of the page.
  • In addition, we added support for smart zoom. Double-tap with two fingers on your trackpad, or with a single finger on your Magic Mouse, to zoom the content below your cursor into focus.
  • Native context menus: Context menus on macOS are now native and support Dark Mode.

WebRender is now enabled on Linux with the Nvidia binary driver and on all desktop environments

Fixed

  • Colors in Firefox on macOS will no longer be saturated on wide gamut displays, untagged images are properly treated as sRGB, and colors in images tagged as sRGB will now match CSS colors.
  • In full screen mode on macOS, moving your mouse to the top of the screen will no longer hide your tabs behind the system menu bar.
  • Also in full screen mode on macOS, it is now possible to hide the browser toolbars for a fully immersive full screen experience. This brings macOS in line with Windows and Linux.
  • Various stability and security fixes.

Changed

  • Introducing a non-native implementation of web form controls, which delivers a new modern design and some improvements to page load performance. Watch for layout bugs in web pages that make assumptions about the dimensions or styling of form controls.
  • The screenshots feature is available in the right-click context menu. You can also add a screenshots shortcut to your toolbar.
