Firefox extension to list the hosts, and corresponding IPs, from which a page and its resources are loaded.
AMO listing: https://addons.mozilla.org/en-US/firefox/addon/ipvfox/
IPvFox is essentially a Firefox version of the Chrome extension IPvFoo: http://code.google.com/p/ipvfoo/ although they're by different authors and don't share any code.
Run make
. The included Makefile requires 'zip' and is tested on Cygwin, but
it ought to work on Linux too.
Alternately, you can just zip up the contents of ext/ into an .xpi file.
The Makefile will leave you with two files in build/: an XPI and a proxy file.
The XPI file can be installed by dragging/dropping it onto Firefox, but if
you're planning on doing some hacking, you should instead copy the proxy
file to your Firefox profile's extensions/ folder. The extension will then be
loaded directly from wherever you ran make
.
