Firefox Plugin To Analyze Web Page Speed And Page Speed Activity
Earlier today I was looking around Google’s Webmaster Tools site which allows you to add various web sites and analyze data obtained via the Googlebot search engine spider. If you are not familiar with the Google Webmaster Tool site then click here to explore all of the data that is available to you for each of your web sites. Anyhow in the process of looking around the Webmaster Tools site I noticed a Firefox plugin called Page Speed in the Labs portion of the Webmaster Tools site. This plugin provides similar functionality to Safari’s Web Inspector when combined with the required Firebug Firefox plugin. Below is information on installing the Google Page Speed Firefox plugin as well as basic usage information including some screenshots of the plugin in action.
