Firefox adds 'Shake to Summarize' AI page summaries on iOS
Firefox is adding 'shake to summarize' — shake your iPhone (or tap the thunderbolt icon) to get an AI-generated summary of the web page. On iPhone 15 Pro or newer with iOS 26 it uses Apple’s on-device AI; older iOS uses Mozilla’s cloud. Works on pages under 5,000 words, US/English initially; opt-out available.
