" summary

Page Speed is a Firefox/Firebug add-on and open source toolkit (code.google.com/pagespeed) that analyzes real pages and produces actionable fixes: unused JavaScript functions (runtime tracing rule, off by default because it slows loads), lossless image recompression with downloadable optimized images, JS minification, and CSS selector efficiency checks based on Mozilla guidance. Released June 4 and hits 100,000 downloads in 10 days, includes an Activity Panel showing DNS, TCP, JS parse/execute hotspots (BBC and Gmail examples), and now supports Firefox 3.5.
