JSONView add on for Firefox

Dynamically-generated JSON is bread-and-butter to modern AJAX development, but it can be irritating and slow to pick through a compressed lump to try and work out what’s really going on. Finally, I got annoyed enough to install a Firefox plugin to “pretty print” JSON (with expand-contract handles) in a browser window.

In general it’s good at what it does. It would be nice to have a few more options, such as a way to tell it what mime-type(s) to consider as representing JSON, and enough intelligence to ignore common “wrapping” JavaScript such as a variable assignment.
