HSFirePHP! tries to queue all FirePHPCore logging statements and to rebuild them after page redirection which is used by Joomla! to execute tasks.
However some information - especially on trace - cannot be queued and thus not rebuild after page redirection either.
For Firefox the FirePHP extension needs to be installed and activated.
For Chrome the FirePHP extension needs to be installed and activated.
All data is sent via response headers and will not interfere with the content on your page.
HSFirePHP! is ideally suited for AJAX development where clean JSON and XML responses are required.
Warning: Using HSFirePHP! on production sites can expose sensitive information. You must protect the security of your application by disabling HSFirePHP! logging on your live site. You can do this by restricting HSFirePHP! logging to authorized users only.
