Page Speed Firefox/Firebug Add-on

Page Speed is an open-source Firefox Add-on integrated with Firebug developed by Google. Webmasters and web developers can use it to evaluate the performance of their web site and to get suggestions on how to improve them.

This tool performs several tests on a site’s web server configuration and front-end code. These tests are based on a set of best practices known to enhance web page performance and can be used to get a set of scores for each page, as well as helpful suggestions on how to improve the web site’s overall  performance.

By using this information, you can:

  • Make your web site faster.
  • Keep Internet users engaged with your site.
  • Reduce your bandwidth and hosting costs.

SDK for developers

Developers can use the SDK to generate scores and suggestions in environments other than the Page Speed Firefox browser Add-on. Learn more.
