Firefox will soon let you shake your iPhone to get an AI-generated summary of the webpage you’re on. The feature rolls out this week, and will operate using Apple’s on-device AI model on the iPhone 15 Pro or newer once iOS 26 launches.

On older iOS versions, Mozilla will use its own cloud-based AI system to create summaries and insert them on top of the webpage. Along with shaking your phone, you can also access AI-generated summaries by tapping the “thunderbolt” icon in the address bar, or tapping the three dots at the bottom of your screen and selecting “Summarize page.”

Mozilla notes that you can turn off the feature at any time, in case you don’t want the browser to misinterpret a fumble of your phone as a summarization request. Shake to summarize will only work on webpages with fewer than 5,000 words.

With the launch, Firefox will become one of the first major third-party apps to roll out an integration with Apple Intelligence, which we may hear more about during today’s iPhone launch event. Shake to summarize is only available in the US and in English to start, but Mozilla plans on expanding it globally and to Android users in the future.
