Unlike Firebug and TamperData HttpFox does not change behavior of the browser cache, and correctly reports what is being served from cache and what goes on the wire. Unlike TD and LiveHTTPHeaders it has a convenient user interface for examining HTTP conversation post-factum, including timing, cache info, etc. The interface part follows from it being a direct, if not yet complete clone of HttpWatch, an excellent commercial product for IE. Unlike tcpdump/tcpflow/wireshark it allows convenient capture of SSL traffic, and is quick to use. In summary, HttpFox is the a great tool for HTTP optimization under Firefox.
