The JSON viewer is new in Firefox 44.
|
|
|
|
Before Firefox 53, the JSON viewer is enabled by default only in Firefox Developer Edition and Firefox Nightly. To enable this feature in other release channels, set the ```devtools.jsonview.enabled``` preference to ```true```.
|
|
|
|
From Firefox 53 onwards, the JSON viewer is also enabled by default in Beta and the normal release version of Firefox.
|
|
|
|
|
|
Firefox includes a JSON viewer. If you open a JSON file in the browser, or view a remote URL with the Content-Type set to application/json, it is parsed and given syntax highlighting. Arrays and objects are shown collapsed, and you can expand them using the "+" icons.
|
|
|
|
The JSON viewer provides a search box that you can use to filter the JSON.
|
|
|
|
You can also view the raw JSON and pretty-print it.
|
|
|
|
Finally, if the document was the result of a network request, the viewer displays the request and response headers.
