Mozilla finally brings Shake to Summarize to Firefox on Android

Mozilla has finally brought Shake to Summarize, a feature it introduced last September on the iOS version of its Firefox browser, to Android.

Shake to summarize is an AI feature that generates a clean summary of a webpage by shaking your phone, as long as the website has fewer than 5,000 words. If you prefer not to shake your device, you can also find a "Summarize Page" option by tapping the three-dot menu in the browser. The AI can adapt its output based on the content. So if you're on a recipe blog, for example, it will smartly extract just the cooking steps, and on a sports page, it pulls the final scores.

TIME Magazine gave the feature a special mention last October, adding it to the publication's list for the Best Inventions of 2025.

Now that Shake to Summarize is on Android, its summaries are handled by Mozilla's cloud-based AI, which the company says runs on a Mistral-Small model selected for its efficiency. This is a different approach from the iOS version, where Apple Intelligence handles the processing completely on-device for anyone using an iPhone 15 Pro or later running iOS 26, meaning the text never leaves the phone.

Apart from now supporting Android, the feature is getting more languages on iOS. The list now includes German, French, Spanish, Portuguese, Italian, and Japanese. The Android version, however, remains English-only for now, though Mozilla has stated that support for more languages is coming soon.

Firefox itself may soon be getting a major redesign on desktop under the codename "Nova". Early mockups for a project codenamed "Nova" appeared online back in March, showing a complete visual overhaul that follows previous redesigns like 2021's "Proton".

The new design language uses aggressive curves on its tabs and address bar, creating a softer look with floating "island" UI elements. It also introduces a dynamic color system, similar to Google's Material You, that extracts hues from your desktop wallpaper.
