Firefox introduces a new “shake to summarize” feature for iPhones, leveraging Apple’s on-device AI to generate concise summaries of webpage content. This feature launches alongside iOS 26 and is compatible with iPhone 15 Pro and newer models. Users can also tap a “thunderbolt” icon or a menu option for summaries. Initially available only in the U.S. and English, Mozilla plans future expansions globally and to Android users, enhancing user engagement.
