29.5.2018
Working around Firefox at Mozilla means that you need to get acquainted with mercurial, the version control system that rivals git and svn. Like any tool, hg (mercurial) can be difficult until you’re well versed with it. And if you hg import a URL that doesn’t match up with...

Regain Disk Space from Homebrew
21.5.2018
One of my favorite utilities is Homebrew, the shell utility for installing and upgrading other utilities — it’s a lazy developer’s dream. Dreams can easily turn to nightmares, however, and I recently learned that Homebrew caches older versions of installed packages, leading...

Responsive tables, revisited
16.5.2018
Lea Verou with some extra super fancy CSS trickery. No way we could miss linking this one up!
One of the problems with responsive table solutions, at least the ones where you are using CSS to rejigger things, is that there is duplicated content somewhere. Either in CSS or HTML.
Lea finds two ways...
Detect WebVR Support with JavaScript
16.5.2018
It’s been two years since I was heavily involved with WebVR at Mozilla but, despite not contributing every day, I can see VR making leaps and bounds, from Firefox making an increased effort to Chrome pushing VR and Oculus and HTC (Vive) improving their offerings. Native games are getting...

Get a React Component by DOM Node
15.5.2018
Retrieving a React component’s DOM node is fairly simple from within the component itself, but what if you want to work backward: retrieve a component’s instance by DOM node? This is a task that the old Dojo Toolkit’s Dijit framework allowed with the dojo.byId method, so it made...

How to Get a React Component’s Element
14.5.2018
JSX is an amazing pseudo-language for React, and if I’m honest, it’s what brought me to love React so much. Using React without JSX is cumbersome and frustrating, while using JSX is such an easier way to express your code. One drawback of JSX, however, is that it makes accessing...

Vertically Centering with Flexbox
8.5.2018
Vertically centering sibling child contents is a task we’ve long needed on the web but has always seemed way more difficult than it should be. We initially used tables to accomplish the task, then moved on to CSS and JavaScript tricks because table layout was horribly inefficient —...
React and autofocus
7.5.2018
While I love ReactJS, I can say that I sometimes find interactions that were easy during the pre-ReactJS are annoyingly difficult or at least “indirect”. One example is properly ensuring that a given <input> element gets focused when a button in a different component...
CSS Environment Variables
4.5.2018
We were all introduced to the env() function in CSS when all that drama about "The Notch" and the iPhone X was going down. The way that Apple landed on helping us move content away from those "unsafe" areas was to provide us essentially hard-coded variables to use:

Change Python Version
1.5.2018
Python plays a major role at Mozilla; much of our website backends and tooling are written in the powerful language. Want to build Firefox? You’ll need to make sure you have the proper Python version, which I recently found out had been upgraded. Despite installing and verifying I had...
