AMF Explorer is an AMF data viewer which can be used to view the deserialized AMF requests and responses. The addon lets you see the requests and responses in the ‘Net’ panel of Firebug. You need to have Firebug addon installed in your Firefox.
Here are the URLs.
This lets you see the AMF data as you used to (I used to) see using the Charles HTTP proxy application. Charles is not free and the evaluation version shuts down in every 10 minutes or so. Give it a try. Its still version 0.6 so more features may be pending.
Update: Few screen shots.
