Source Website Optimization: Page Speed For Firebug

Page Speed is a new and interesting website optimization add-on for the Firefox Firebug extension. This means that Page Speed requires the Firefox web browser and the Firebug extension for Firefox before it can be installed. Two new tabs will be added to the Firebug menu which can be used to analyze the performance of the active website.
The Page Speed tab can be used to analyze the active website. A website optimization report will be generated that groups the findings into priorities. The high and medium priority groups list elements that should be optimized to increase the performance of the website. Low priority items on the other hand are fully or partially optimized items that can still provide some performance gains but not as much as the medium or high priority items.
