issue with firefox tamper data plugin

I am facing this p开发者_运维问答roblem while debugging a website.

Plugin used: tamper data for fire fox;

Possibilities: its a ajax request.

as you see in the image the tamper dialog dose not show anything for this request. for other request it shows the general options.

any known issue with this.

And I also want to know if any other better tool available for analyzing websites(live or remote, not on localhost)

Tamperdata is the buggiest thing ever made, even the UI takes 50 clicks to do anything. Look for another tool. I personally use HackBar to send simple POST/GET requests (there's a version that can modify cookies per request too I think), and Wireshark or livehttpheaders (although livehttpheaders is also buggy) when I need to analyze traffic.
