This is great and highlights one of the most common mistakes developers make since became easier to server render framework sites - rendering buttons etc before the JS has loaded to make them work.

JS promise integration for WebAssembly landed in Firefox 153, making it easier to work with asynchronous calls from Wasm. Here's how it works:

We are going to spend the next 20 years discovering and dealing with the mental health effects of over-reliance on AI.

JS text imports landed in Firefox 153, making it the first browser to support this feature. Here's how it works:

I made an accessibility error when coding up some tooltips. Here's where I went wrong, and how you can avoid making the same mistake: jakearchibald.com/2026/my-tool...

During the F1 race on Sunday I said "I… think one of the bridges is CGI" and no one believed me. But they absolutely did. It's 'missing' from the onboards too.

"poopover" was right there.

By Cory Doctorow (GPG 0xBF3D9110957E5F4C)@doctorow.pluralistic.net · 2w ago

One of 2026's better tech-related coinages is "dickover," John Gruber's term for > a modal panel, popover, or curtain presented by a website or app, deliberately obscuring its own content to frustrate the user with an unwanted, unnecessary, mandatory interaction... 1/

Dang they really got a category for everything

Discovered that aria-describedby doesn't work on VoiceOver in Firefox or Safari unless the element with the attribute has a role like image/link/button or it's a form field. bugzilla.mozilla.org/show_bug.cgi... bugs.webkit.org/show_bug.cgi...

If you make websites for a living, stop what you're doing and read this research by @tammyeverts.com; it shows what many of us have been saying for a long time: even if there is such a thing as "fast enough", it's generally *much* faster than you are targeting: embrace.io/blog/research-co…

New research: The Core Web Vitals thresholds you trust might be wrong for your site

Core Web Vitals data from ten leading online retailers reveals that "good" for Google may not be good enough for your users or your business.

Firefox now supports the text-box-trim and text-box-edge CSS properties, and the associated text-box shorthand. These properties allow you to control the leading space above and below text, enabling simpler and consistent vertical spacing and alignment. bugzilla.mozilla.org/show_bug.cgi...

This is a wild one. Watch out if you have a top-level wheel listener (which React always adds) and use the navigation API.

Ivan Akulov@iamakulov.com · 3w ago

Possibly one of the most impressive Safari bugs I’ve run into lately: Going back (with a swipe) in *any* React app that uses Navigation API freezes the page for three seconds. What’s fun is the main thread is not frozen, only the rendered page is.

Event Horizon is (I'm told) a deeply flawed film but I absolutely loved it and it scared the shit out of me as a teenager. Neill was brilliant in it. Glad to see it represented here.

Yashar Ali 🐘@yasharali.bsky.social · 3w ago

The legendary Sam Neill has died. He was 78 and had been battling stage 3 blood cancer, but announced in the spring that he was cancer-free. His family described his passing as “sudden and unexpected.”

counterpoint: the dead should make it harder for me to speak ill of them

Notification actions landed in Firefox 152, allowing you to add quick action buttons to your notifications. Here's how they work:

@pfrazee.com video uploads are consistently failing. They fail immediately in Firefox, and in Chrome they seem to upload then fail.

I know I've said this before, but I love how good libaom-av1 is at encoding screen recordings. The last video on jakearchibald.com/2026/goldilo... is HD, 60fps, 22 seconds, and 165kb.

Right now, if you import something from JS, and the result is a 404 (or other not-ok status code), it fails the load & gives you nothing. I wonder with json imports, and maybe even text/byte imports, if that's the right pattern github.com/whatwg/html/...

This is great, but I'd add that anchor positioning is pretty unreliable due to frequent spec changes, ambiguities, and buggy implementations (my recent blog post demos fail in Safari despite it all being Level 1 stuff). It's a powerful feature, but if you struggle with it, it's not your fault.

Josh W. Comeau@joshwcomeau.com · 4w ago

Just published a blog post about the new CSS Anchor Positioning API! ⚓ I’ve been learning about it over the past few weeks, and it’s friggin’ great, but it also took me a minute to really get the hang of it. My goal in this post is to share the most useful bits, so you can start using it today. 🔥

People who spiral out overusing LLM chatbots are really just experiencing the kind of brain-damaging stream of unconditional validation that’s always been the norm for the hyper-wealthy, which explains a lot.

Worse than Twitter, private discussions (text, email, whatever) among like-minded wealthy lunatics who are all surrounded by yes-men who talk like ChatGPT in maximum ass-kissing mode.

There's an ideal set of sizing constraints for custom <select>, but the CSS is a bit tricky. Here's how to make it work, and a tour of new CSS features along the way. jakearchibald.com/2026/goldilo...
