ECMAScript excitement 😉 Congrats to my coworker @ashley-c.bsky.social at TechAtBloomberg on advancing Await Dictionary to Stage 2.7 at TC39 today 🎉 Promise.all returns positional results as an array. Promise.allKeyed allows named results inside an object 👍 github.com/tc39/proposa...

So first off someone update these people about what "punk" means in this context, but second I beg you to understand that people doing these things around old school punks would quickly experience what can only be called a very sharp reminder of the fragility of the human occipital bone

The @firefoxdevtools.bsky.social JSON viewer got better in @firefoxnightly.bsky.social : the console offers access to the original json data via `$json`. This allows to easily manipulate the underlying data to get what you want

#HTML is only as accessible as you write it. Semantics determine what an element is, and browsers provide some interactive behavior for native interactive elements for free. But just because two patterns have similar behavior doesn't make them semantically the same.

Sanitizer API is now enabled by default in Firefox Nightly. bugzilla.mozilla.org/show_bug.cgi... developer.mozilla.org/en-US/docs/W... Still behind a flag in Chrome Canary...

New in Firefox nightly (146.0a1 2025-10-19): large lists of unused CSS custom properties are collapsed by default. This not only reduces clutter, it also massively speeds up the rendering of the inspector panel in some cases.

We're currently working on devtools for view transitions in Firefox, but in the meantime, here's a little-known option that helps…

Here's how we handle manchildren on the Steam forums at No More Robots:

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most. So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion. interop-rank.jakearchibald.com

Connaissez-vous Neama Hassan ? Elle est une poétesse gazaouie qui cherche refuge en France. Une cagnotte pour l'accueillir existe mais elle n'en est qu'à 60% et elle ferme dans deux jours. Je suis sûre que nous pouvons aider à ce qu'elle soit plus remplie ! www.helloasso.com/associations...

Another #Swordtember Overgrown gothic. Found in the ruins of a temple to a long-forgotten god, the blade seems to be made from the same stone as the building. This stone holds an edge unlike anything I’ve seen, and the blade is still sharp. #HumanArtist

For anyone who pays attention to high contrast / forced colors mode styles: I wrote up an explanation of why forced-color-adjust: none is nearly unavoidable and how it sets up your codebase for downstream bugs: sarahmhigley.com/writing/forc...

A Xiaomi SU7 has been seen in Paris, and I'm sorry but I'll (continue to) call it Xiaomi Sucette (the french word for lollipop, like chupa chups), and I'm certain I'm not alone…

Yay! It's the first Firefox release since I've joined the team, so let's take a look at some of the new developer-facing features in Firefox 142… 🧵

Randomness in CSS!! Please try it out and give us some feedback: webkit.org/blog/17285/r... :)

View Transitions are enabled by default in Firefox Nightly, so they're on their way to stable. Give it a test with your current transitions, and give me a shout if anything doesn't look right.

Well, I’m not far from 40 and I also support this terminology.

We've got a good-first bug for new contributors to Firefox: bugzilla.mozilla.org/show_bug.cgi... If you're interested in writing a little bit of C++/HTML/JS to make your first contribution, let me know! I'd be happy to guide you through the whole process over chat or video call.

Starting my new role on Monday. Could be anywhere.

Most of the internet used to be like this. This is actually the default, it took companies enclosing the internet and adding weird, soul-killing incentives to make people behave the way they do now. In a way, there is truly nothing special about Wikipedia except that it survived longer.

Bon à ce stade je suis un peu désespérée... Je suis à la recherche d'une alternance en maison d'édition au poste d'édition/ technicien de fabrication. Si vous connaissez des gens qui travaillent dans le milieu et qui recherchent/ seraient aptes à prendre des alternants...

I love CSS folks. They are soldiers of joy and delight. The world is burning and AI debates have people at each others throats and CSS peeps keep being like “check out this dancing turtle I made out of divs 🥰”

Just found out Replit's slogan is (or was?) "vibe code, safely", and they boasted about it just 1 week ago. Karma is a bitch www.linkedin.com/posts/repl-i...

well i followed the stack trace — for days i followed it, out of the console & over alpine tundras; through thick, burly woods & thin scraggly fields and now i'm here, this magnificent, desolate desert. mighty sandstone towers with Navajo names rise high on distant horizons, imposing, brave, fragile

Matt Turnbull, Executive Producer at Xbox Game Studios Publishing - after the Microsoft layoffs - suggesting on Linkedin that may maybe people who have been let go should turn to AI for help. He seriously thought posting this would be a good idea.

If you've ever woken up and wondered "what noises are normal for my fridge to make, and how do they compare to other noises I might be familiar with in my day-to-day life?", Electrolux has got you covered. Tag yourself, I'm "BRRR! - noise a cat makes while stretching".

Hot off the presses! Firefox Nightly (www.mozilla.org/en-GB/firefo...) adds the new :heading pseudo! Easily style all headings, or use nth-child-like AnB syntax to select a range of headings! Needs `layout.css.heading-selector.enabled` flag enabled. Try it out and let me know your thoughts.

Practical Retrofitting for Obsolete Devices: nologos.net/slides-limit...

Had a fantastic time at Annecy last week, was great to meet up with old and new friends. Inspired me to do a little comfort zone painting based on a castle we saw while cycling around the lake🌞

Hello @sachagreif.com , not sure if this known but the MDN/CanIuse buttons/links in the "Reading list" section at the end of the State of CSS survey aren't working (survey.devographics.com/_vercel/insi... is 404ing, maybe that's why?)

They’ve been taught, and many believe, that writing is just having the idea. And are in for a rude awakening when they try to break into the industry. I’ve read a lot of game screenplays as a hiring manager. I never judged the IDEA; it was all about the writing quality and characters

Firefox 139 includes an update where content inside a <details> element is included in an in-page search. Previously, that content was ignored when the element was in a closed state. www.mozilla.org/en-US/firefo...

Bravo à ces deux héroïnes :

I did it. I blogged again! This time, I wrote about what Developer Advocacy looks like in 2025.

“Drew an uppercase to this psychedelic blackletter” hmmm that’s not gonna take off. “It’s the way I drew an uppercase to this psychedelic blackletter for me”

With @firefox.com 138 just around the corner, did you noticed some of the changes we made in 137? Find out in our latest blog post: fxdx.dev/firefox-devt... #devtools #html #css #js #network
