JSONView is a Firefox extension that helps you view JSON documents in the browser.
Normally when encountering a JSON document (content type "application/json"), Firefox simply prompts you to download the view. With the JSONView extension, JSON documents are shown in the browser similar to how XML documents are shown. The document is formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text.
Once you've got JSONView installed, check out this example JSON file to see the extension in action!
CouchDB users and others who need to have "application/json" sent in the HTTP Accept header to serve JSON properly should set that option in JSONView's options panel. Be aware that telling sites that you accept JSON can mess up some sites that don't expect it.
If you'd like to contribute to JSONView but don't want to code, consider contributing a translation. Just go to BabelZilla and register as a translator for the JSONView extension. There's not much there to translate!
