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.

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, and this is wrapped up in Firefox 62, 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.

Mo’ Pixels, Mo’ Panels

Do you have a 4k monitor? Do your browser windows bathe in a wash of ample screen real-estate? Let your devtools stretch their legs with a new 3-column mode in the Page Inspector. You can now pop the CSS Rules view into its own column, to let you view style information and the excellent Grid tooling or Animations panel side-by-side.

What's New:

The latest version of Mozilla’s Firefox browser, out now for Windows, macOS, Linux and Android, now blocks third-party tracking cookies and cryptominers by default.
