If a Data Saver user is on a 2G-speed or slower network according to the NetInfo API, Chrome disables scripts and sends an intervention header on every resource request. Users are shown a Lite Mode UI in the omnibox. Users can enable scripts on the page by tapping “Show original” in the omnibox UI. An intervention report is sent when this optimization occurs.
