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.

New:
- The baseline interpreter for JavaScript bytecode execution is now enabled
- The developer tools accessibility panel now includes an audit for keyboard accessibility
- The developer tools accessibility panel now includes a color deficiency simulator for systems with WebRender enabled
- When focused on a toolbar button, users can now type the first (or first few) characters of another button's name to jump directly to that button.
- Inactive CSS: The Inspector now grays out CSS declarations that don’t affect the selected element and shows a tooltip explaining why.
Fixed:
- macOS: Vastly reduced power consumption with a more efficient compositor
Changed:
- Built-in Firefox pages now follow the system dark mode preference
- WebRender enabled by default for Windows desktops with Integrated Intel graphics for Low Resolution devices
- Aliased theme properties have been removed, which may affect some themes
- The Firefox Accounts toolbar menu has been updated and reorganized to give faster access to account features and services.

- Firefox now supports the CSS properties 'text-decoration-thickness' and 'text-underline-offset', which let web developers control the position and size of text decoration lines.
- Firefox now supports the CSS property 'text-decoration-skip-ink', which (by default) makes underlines and overlines skip over any text that they intersect, to improve readability.
- DOM Breakpoints in Developer Tools allows diagnose with code in a page changes a specific DOM node, including the node's children

On August 2, 2016, Firefox 48.0 was released. It is scheduled to be replaced by Firefox 49.0 on September 13, 2016. At that point, Mac users using OS X 10.6 Snow Leopard, 10.7 Lion, and 10.8 Mountain Lion will be left behind by the current versions of Firefox. It will be a sad day, as Firefox is the last major browser to support Mac OS X 10.6 through 10.8.
But it’s not all bad news. Firefox has given us Mac support longer than Google’s Chrome browser, which left us behind in April 2016. And in comparison to Apple’s Safari browser, Chrome and Firefox have been downright generous. Safari 5.1.10 was the last version for OS X 10.6, and that arrived on September 12, 2013. Safari 6.1.6, the final revision for OS X 10.7, was unleashed on August 13, 2014, and 6.2.8, the last version for OS X 10.8, a year later on August 13, 2015.
Chrome gave Snow Leopard users 2-1/2 years more support than Apple did, Lion users 20 months more, and Mountain Lion 8 months. When Firefox 49.0 arrives, Snow Leopard users will have had 3 years more support by Firefox than Safari gave them. Lion users, 25 months, and Mountain Lion holdouts, 13 months.
Outdated Does Not Mean Obsolete
Fear mongers will insist on running the latest version of browser on a fully up-to-date operating system with the belief that anything else puts you at risk. The truth is, there are unknown risks in the latest software. You can never be 100% secure.
However, you can be very productive with older operating systems, applications, and browsers. Just because some new piece of software requires a newer OS version is no reason to upgrade – unless it gives you a feature you really need to have. I have been happily working with OS X 10.6 on my 2007 Mac mini for years. I use Safari, Chrome, and Firefox daily on it, and only one of them is current – and not for much longer.
Then again, OS X Snow Leopard itself is far from current, yet it allows me to run lots of software and be very productive. I don’t find it limiting at all to use outdated software with an outdated operating system on a discontinued computer that will never run OS X 10.8 or newer. It’s good enough for what I need it to do.
Honestly, that’s the whole point of Low End Mac. You can be productive even if you can’t run the latest Mac OS and browser. After all, there was a time when they had nothing newer to use, and they were productive then.
The Real World
Security experts will count out hundreds or thousands of security issues with whatever you’re doing on your computer, and none of it matters until someone targets that issue in a way that reaches your machine. That’s the real world. Theoretical security problems are not real until they become exploits, and even then the problem might never reach your system if you’re not downloading apps from unreliable sources.
