Add-on summary
Open web pages with JSON content or JSON files to view, edit, format, repair, query, transform, and validate JSON directly on the browser.
Features:

- View JSON as formatted text.
- View JSON as a table, for top-level arrays or nested arrays.
- Search and replace
- Undo and redo actions
- Edit the JSON keys, and values, copy, paste, duplicate, insert, or remove
- JSON formatting and minifying
- Query JSON with plain JavaScript or using the built-in form
- Sort, filter, and transform JSON
- Handle large JSON documents up to 512 MB
It uses the powerful https://github.com/josdejong/svelte-jsoneditor/ and the Manifest V3 for enhanced security, privacy, and performance.

Great UI of this addon, but can't find a way to save Key or Value entries using firefox v.123 - no Save menu-option shows, and ctrl/s saves the json file but without additions or changes to any values?!
