I'm currently using HTTP Analyzer V5 trial version which expires very soon.

Are there any [good] free tools for sniffing and inspecting the contents of HTTP packets, in a similar way to the above mentioned tool?

A: 

Many of the tools at Ways to See SOAP Traffic are free.

I personally use wireshark with the HTTP filter.

Personally, I like Fiddler the most.

Fiddler2 has saved me sooo much time in the past, Web Services Studio too for analysing what soap messages are going back and forth to a web service.

Does it only sniff on IE?

Fiddler can act as a local proxy for other browsers too. By default, it hooks up to IE automatically, thats true, but you can setup other browsers manually.

To look inside TCP/IP packets and view the full bits and bytes, I recommend Wireshark. To look inside the HTTP protocol transmissions, Fiddler2 suffices.

Whilst using wireshark for in-depth examination, for more lightweight analysis I also use the httpfox addin for Firefox and, more occasionally, the Live HTTP Headers addon for Firefox. httpfox aims to include the functionality found in httpwatch.
