This extensions displays some technical and structural performance data of websites.
This extension determines and displays some very useful performance data of websites in a quick and easy way. Just open the website you want to inspect, click the icon in the browser bar and a popup shows up.
The popup will show performance data like: DNS Lookup Time, Network Connection Time, Time to First Byte, Document Ready and Document Complete. It also shows some performance information in terms of the DOM, such as number of external files (Javascript, CSS) or number of DOM elements. And finally there is a panel for memory usage of Javascript execution.
This extension will give you the possibility to get a quick overview of the performance of a website and to compare it with other sites.
Feedback is very welcome! If you have some feedback or ideas for additional information to show in the popup, don't hesitate to contact me.

- Great tool !!! To see true data you have to delete browser cache and do an "hard reload" - You can do so by hitting the F12 button and right clicking the refresh button!

- Useful too! I noticed that the information under "DOM structure and Elements" is correct, but the "Website Speed" information is in-accurate.
