Description from store
View results by opening the Developer console (More tools -> Developer Tools -> Console).
This plugin runs on every page and triggers after pages finish loading. It measures advanced web quality metrics show results on the console view, with options to save results to disk. It calculates the time instant metrics: DOM, PLT (onload), and ATF load time. It also calculates time integral metrics, similar in spirit to Google's SpeedIndex, but measuring load completion of objects (ObjectIndex), bytes (ByteIndex) and images (ImageIndex). The relation between these metrics and perceived quality can be found in our tech-report "Narrowing the gap between QoS metrics andWeb QoE using Above-the-fold metrics", available in our project page: http://perso.telecom-paristech.fr/~drossi/index.php?n=Dataset.WebMOS

- (2020-11-17, v:1.20) mark ahlenius: Deprecated warnings when using Approximate ATF extension
Hi, I've just found out about this extension and when I installed it, on Chrome Version 86.0.4240.198, the Chrome console immediately complains about some deprecated function calls. like: (Deprecation) chrome.loadTimes() is deprecated, instead use standardized API: Paint Timing... (Deprecation) "HTMLVideoElement.webkitSupportsFullScreen" is deprecated, Please use 'Document.fullscreenElement' instead... ... And then the ATF_img: value is 0.0, but the actual page ATF tile was ~8 secs for apple.com. Is this extension still being supported and if so, is there any chance of getting this resolved? thank you, 'mark - (2018-07-12, v:1.20) mwxseo Sammelaccount: My output doesn't contain the ATF metric, as shown on screenshot
