HttpFox: The Firefox HTTP Headers Monitor Addon
HttpFox is a great Firefox addon that monitors the live HTTP traffic sent and received by the mozilla browser. If you are a Firefox Web developer you will certainly love it as it will give you an insight look on what and how your Firefox browser is communicating with the HTTP server software. It enables you to profile web server responses (HTTP response headers and response codes) and dig into the headers to check out cookies involved in the requests as well as POST parameters.
HttpFox can also inspect secure HTTP (HTTPS) queries which are not easily accessible in protocol analysis software.
In addition to the features mentioned aforehand, HttpFox addon can also capture and reveal the following informations from live HTTP headers as well as HTTPS headers:
-Time and duration of the HTTP request
–HTTP status codes (also called HTTP response codes)
-HTTP method (POST/GET)
-Duration of the HTTP request
The filter field can be used to search for a particular URL in the captured data.
Please note that HttpFox can’t be used for data tampering.
