Handy Rated 5 out of 5 stars

Very handy for debugging JSON data used on various web sites (including my own). You need to make sure you set the content type correctly on the server to make the highlighting work.

The pretty printing is really sweet since most of the time my JSON is compacted and unreadable.

To be honest, it would be great if this functionality could be encorporated in the web developer toolbar extension...

This review is for a previous version of the add-on (0.6).
