I am having a problem getting the POST data from a Facebook action. When you submit a comment on FB it posts to this url: https://www.facebook.com/ufi/add/comment/?__pc=EXP1%3ADEFAULT In the request, the post data for the post exists: Here is an example of the actual comment from the post data:
comment_text:test this is a test
When I try to access this through a Chrome Extension I can't seem to get this data. I've tried parsing the requestBody, but it is empty. I then tried to see if any of the other requestmethods would work, and I can't seem to find the data anywhere.

Any other listener not listed above didn't have output.
Anyone have any idea here?

Your console.log shows that requestBody is not empty.
You'll just have to parse the raw bytes:
If the request method is PUT or POST, and the body is not already parsed in formData, then the unparsed request body elements are contained in this array.
For example if the posted data is a string then you can get its value in onBeforeRequest listener:
var postedString = decodeURIComponent(String.fromCharCode.apply(null,
new Uint8Array(details.requestBody.raw[0].bytes)));
There are many methods to decode the string depending on the encoding used by the site script.
