Add-on summary

Analyze keywords

Firefox has a built in JSON viewer, but it didn't always. JSONView was built to display JSON documents in an easy to read format, which is still nice if you don't like the default viewer. 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 http://jsonview.com/example.json to see the extension in action!

As of the recent update I've noticed a rather breaking change. My API returns json with very small numbers: eg "transform": [ 4.371139e-8, 1.080646e-7, ] As of the recent update, this now shows up as: "transform" [ 4, 1 ] Which is totally wrong, if you round to 0 it would be more acceptable, but rounding to 4 and 1 in this case is totally wrong and actually caused me to have a panic attack this morning thinking all our data was suddenly corrupt. Could you please provide a patch fix for this soon, as I love the other features of this plugin. EDIT: looks like you already noticed: https://github.com/bhollis/jsonview/commit/a6692b8d20b6d88524395887e66e25ee7757e2bd 41 minutes ago haha
