Mozilla has introduced Shake to Summarise for Firefox on iOS in the United Kingdom. The feature lets users generate summaries of web pages using AI by shaking their iPhone or tapping a specific control within the browser.
Support for Android devices is expected later in 2026. These summaries are tailored to the content type: recipes show step-by-step instructions, sports pages display scores and statistics, and news articles highlight key points from the text.
On-Device vs. Cloud Processing
On iPhone 15 Pro models and later, running iOS 26 or newer, summaries are created locally on the device using Apple Intelligence, so page content stays on the phone. Older iPhone models or those with earlier iOS versions send page text to Mozilla’s servers, where it is processed into a summary before being sent back to the device.
Mozilla has not provided details about what data is stored after cloud processing or how long page text remains on its servers.
Other Firefox Mobile Features Mozilla Has Planned
Mozilla has announced upcoming features for Firefox mobile set to arrive over the next few months. An AI Controls panel will enable users to manage all generative AI options from one place, including a switch to disable all AI features at once or toggle each one individually.
Preferences will be saved across browser updates. A built-in VPN for Android is also in development, providing up to 50GB of monthly browsing protection on supported platforms. Tab Groups will let users organize open pages into labeled collections, with automatic grouping suggestions planned to help reduce clutter when many tabs are open. Shake to Summarise is now available for Firefox on iOS in the UK.
Mozilla has not announced a release date for other regions or for Android.
