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

![Firefox JSON Viewer opened for the html entites JSON file
We can see the various properties of the JSON file, which are all objects containing a "characters" and a "codepoints" properties.
The Console is opened at the bottom. In it, we can see a console message explaining that some data is available (`$json.data` - the parsed JSON object, $json.text` - the original JSON text and `$json.headers` - HTTP request and response headers)
There's a console evaluation done with the following snippet:
```js
Object.entries($json.data)
.filter(([k, v]) => v.codepoints.length > 1)
.map(([k, v]) => ({characters: v.characters, htmlEntity: k, codepoints: v.codepoints}))
```
and the result shows an array of objects containing "characters", "htmlEntity" and "codepoints" properties.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:l6jizqbrtfnhnrd7vmsqmi3n/bafkreigizqr72frwj6qa53onh2tskqmcmrydexkzeydrkrarwiuoyulcmq@jpeg)

#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.

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.

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.

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

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.
