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.
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.
Firefox 67 demonstrates improved performance thanks to a number of changes such as:
- Lowering priority of setTimeout during page load
- Delayed component initialization until after start up
- Painting sooner during page load but less often
- Suspending unused tabs

Private Browsing sees both usability and security improvements:
- Save passwords in private browsing mode
- Choose which extensions to exclude from private tabs
A myriad of new features help make Firefox easier to use:
- We’ve added a toolbar menu for your Firefox Account to provide more transparency for when you are synced, sharing data across devices and with Firefox. Personalize the appearance of the menu with your own avatar
- Tabs can now be pinned from the Page Actions menu in the address bar
- Firefox will highlight useful features (like Pin Tabs) when users are most likely to benefit from them.
- Easier access to your list of saved logins from the main menu and login autocomplete. Learn about all the ways you can manage your passwords in Firefox.
- The Import Data from Another Browser feature is now also available from the File menu
- Users will be able to run different Firefox installs side by side by default so that you can run the beta and release versions simultaneously
- Users can block known cryptominers and fingerprinters in the Custom settings of their Content Blocking preferences.
- Keyboard accessibility has improved in the latest version of Firefox. Toolbar and toolbar overflow menu are both fully keyboard accessible: keyboard users can now access add-ons, the downloads panel, the overflow, Page actions and Firefox menus, and much more.
- Firefox will now protect you against running older versions of the browser which can lead to data corruption and stability issues.
- Firefox is upgrading to the newer, higher performance, AV1 decoder known as ‘dav1d’.
