Mozilla has introduced the Shake to Summarise feature for Firefox in the United Kingdom. This feature allows users to shake their iPhones or click a specific control within the browser to generate summaries of web pages using AI.

Support for Android devices is expected later in 2026. These summaries are customized based on the type of content: recipes show step-by-step instructions, sports pages display scores and statistics, and news articles highlight key points from the text.

On-Device Processing and Cloud Processing

For iPhone 15 Pro models running iOS 26 or newer, summaries are generated locally on the device using Apple Intelligence, ensuring that page content remains on the phone. Older iPhone models or devices running older iOS versions send the page text to Mozilla's servers; here, it is summarized and then sent back to the device.

Mozilla has not provided details on what data is stored after cloud processing or how long the page text remains on their servers.

Other Firefox Mobile Features Planned by Mozilla

Mozilla has announced upcoming features for Firefox mobile in the coming months. An AI Controls panel will allow users to manage all their generative AI options from a single location; this will include a toggle to disable all AI features at once or to turn each one on or off individually.

Preferences will be saved between browser updates. A built-in VPN for Android is also in development, which will provide browsing protection of up to 50GB per month on supported platforms. Tab Groups will allow users to 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.
