While many users oppose Mozilla"s push into AI, there is simply no escape from it, and some features people may actually find useful. In its official blog, Mozilla announced a new feature for Firefox on iOS: shake to summarize.
Shake to Summarize is now rolling out to Firefox users on iOS. The feature is simple: in TLDR cases (too long, didn"t read), shake your iPhone a bit (don"t drop it), and Firefox will generate a summary of your webpage. Alternatively, you can tap the thunderbolt icon in the address bar or tap three dots > Summarize Page. Mozilla says that page summarization works with articles up to 5,000 words. Here is what the company says about the new feature:
On mobile, browsing often means quick checks on small screens, squeezed in between everything else you’re doing. We built Shake to Summarize on iOS to give you a clear summary with one move. That way, you can get what you need more easily and keep going.
Here is what the page summarization looks like on Firefox for iOS:
Mozilla understands that privacy is very important for its audience, so it provided more details on how Shake to Summarize works. On the iPhone 15 Pro or newer with iOS 26 and newer, Firefox generates page summaries using Apple Intelligence with on-device processing. If you have an older iPhone or one running iOS 18 or older, Firefox will send the page text to Mozilla"s cloud-based AI, which creates the summary and sends it back.
Shake to Summarize will start rolling out to iPhone users today. Initially, the feature is only available on English systems in the United States. If you want to learn more about this feature, Firefox has a dedicated support page with all the details about page summarization and the available settings on iOS.
