Hello PageSpeed users,
We recently decided to deprecate the PageSpeed Insights Chrome extension. The online version of PageSpeed Insights at
http://developers.google.com/speed/pagespeed/insights/ contains the most up to date analysis, and we've been encouraging users to prefer it over the Chrome extension for a while now.
We evaluated trying to update the Chrome extension's analysis to match the online version, but determined that it was a large amount of work, so we've decided to deprecate the extension.
If you are currently using PageSpeed Insights for Chrome, you can continue to do so, but we won't be issuing any more updates and can't guarantee that it will continue to work in upcoming versions of Chrome.
Thanks,
Bryan and the PageSpeed team
