JsonDiscovery от exdis, Roman Dvornov

IMPORTANT! To make JsonDiscovery working, you should disable the default Firefox's JSON viewer:
- Navigate to "about:config"
- In search field type 'devtools.jsonview.enabled'
- Toggle this setting to false

Most exciting features:
- Show JSON as an interactive tree with highlighting
- Easy an object or an array copy to clipboard
- Data structure signature (like in TypeScript)
- Data transformation with a query using Jora, suggestions on a query typing
- Customisation of JSON data presentation (using tables, lists and so on)
- Customisation (report) sharing by a link
- Works on any page with a valid JSON – URL/content type doesn't matter
- Works on local files
- Works offline (doesn't perform any network request)
