JavaScript waitForTime
6.11.2019
I write a lot of tests for new features within Firefox DevTools. We have hundreds of “mochitests” which open the browser and perform synthetic actions like clicking, typing, and other user actions. I’ve previously written about waitForever which essentially halts following actions...

5.11.2019
V dubnu tohoto roku Mozilla oznámila, že se hodlá zabývat otázkou obtěžujících výzev, nabízejících uživatelům možnost zobrazovat oznámení právě prohlíženého webu. Ty se zpravidla objevují v okamžiku načtení webové stránky a uživatel má na výběr mezi souhlasem a trvalým, či dočasným nesouhlasem. Z
Comparing the Different Types of Native JavaScript Popups
31.10.2019
JavaScript has a variety of built-in popup APIs that display special UI for user interaction. Famously:
alert("Hello, World!");
The UI for this varies from browser to browser, but generally you’ll see a little window pop up front and center in a very show-stopping way that contains the message...

Firefox Kiosk Mode
16.10.2019
As someone who loves the HTML and web APIs, I want to see them used in all different types of devices and mediums. Being that I work for the amazing Mozilla Corporation, seeing Firefox and the gecko web engine thrive in those spaces is important to me. Firefox was recently featured in the Firefox...
Scrape the Web with scrapestack (Sponsored)
14.10.2019
I first grew to love Firefox not as a web developer but as user, and what drew me to this amazing new browser was its add-on ecosystem. The add-on I used the most? Web scrapers. Piracy had just hit mainstream and I also need imagery and documentation to create my first websites. Scrapers were...
Zero hands up.
2.10.2019
Asked an entire room full of webdevs yesterday if any of them knew that FF/Chrome/Opera/Brave/etc. for iOS weren't allowed to compete on engine quality.
Zero hands up.

Browser Engine Diversity
24.9.2019
We lost Opera when they went Chrome in 2013. Same deal with Edge when it also went Chrome earlier this year. Mike Taylor called these changes a "Decreasingly Diverse Browser Engine World" in a talk I'd like to see.
So all we've got left is Chrome-stuff, Firefox-stuff, and Safari-stuff. Chrome...

UX Considerations for Web Sharing
20.9.2019
From trashy clickbait sites to the most august of publications, share buttons have long been ubiquitous across the web. And yet it is arguable that these buttons aren’t needed. All mobile browsers — Firefox, Edge, Safari, Chrome, Opera Mini, UC Browser, Samsung Internet — make it easy to share...
Caniuse and MDN compatibility data collaboration

Second only to "silly GIFs," I'd guess screenshots of caniuse are the most common slide graphic at web conferences. It's become the ultimate source for looking at web compatibility data in the hearts and minds of web developers.
