I finally found a more than acceptible Json Viewer for Firefox!
It would be nice to include a configurable expansion level. However, being open source I'll see if I can find some time to contribute.

Thanks for doing and sharing!

fantastic...

一直用chrome下的jsonview查看json数据，在火狐下用这个非常好用，赞

最大的好处就在于加载超大数据量的json数据时，能不把浏览器卡死！
