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.

Just spotted: Firefox Nightly already supports view-transition-class from the Level 2 spec.
A test page that shows which features of the View Transition API your browser supports, here showing Firefox Nightly (142). It supports not only same-document view transitions but also the view-transition-class property that is specified in the Level 2 specification.
