FirePHP

When Ajax techniques became popular, developers faced a new problem: how can we debug Ajax requests and responses efficiently for complex web applications? If using a debugger was hard enough with the RESTful model, triggering an Ajax-specific request is a pain and a bit more difficult; dumping logs and information pertaining to those Ajax operations had to be done using JSON or XML.

FirePHP is an add-on for an add-on: it extends the popular in-browser web development tool called Firebug with an API for PHP web application developers. FirePHP is free and easily attainable via the Mozilla Add-Ons section on the official Mozilla site. The official FirePHP site can be found via this web address: www.firephp.org. Christoph Dorn is the person responsible for creating FirePHP.
