AMF Explorer 0.7
AMF Explorer has been updated to work with Firefox 4 and Firebug 1.7. In the process I also added a the ability to copy the AMF data to the clipboard in JSON format.
The new version is awaiting review on the AMO site, but if you want to get it now you can install it from here: https://addons.mozilla.org/en-us/firefox/addon/amf-explorer/versions/
