How to summarize pages
You can summarize pages in three ways: from the address bar, the page menu, and shaking your device from side to side.
For iOS 26+ users
If you’re using an iOS 26+ device, you’ll also have to enable Apple Intelligence first to summarize pages with your phone in Firefox.
- On your iPhone, go to .
- Tap on .
- Toggle the on.
From the address bar
- Open a webpage for a content type mentioned above.
- If summarization is available, you will see a thunderbolt icon in the Firefox for iOS address bar.
- Tap the thunderbolt icon. (If you touch and hold the icon instead of tapping, you’ll enter Reader View.)
- The page will start to summarize.
From the website menu
- Open a webpage for a content type mentioned above.
- Tap the three-dot menu icon.
- In the website menu, tap .
- The page will start to summarize.
Shake your device from side to side
- Open a webpage with long-form content.
- Shake your device from side to side.
- If summarization is available, the page will start to summarize.
How to adjust settings for page summaries
- Open Firefox on your iPhone.
- Go to .
- Tap on .
- If you switch the Summarize Pages toggle to off, Summarization will no longer be available. Summarize Page will no longer appear as an option in the address bar or website menu. And, you won’t be able to use the shake gesture to summarize pages.
- If you switch the Shake to Summarize toggle off, this turns off the shake gesture. You’ll still have the option to summarize pages from the address bar and website menu.
Frequently Asked Questions
Can I trust the summaries?
Summaries are powered by generative AI, which is predictive technology and not guaranteed to always be accurate. Summaries may have mistakes. You should verify summaries against the original page.
Also, summaries are based on the information within the page. They don’t access other sources for information. If something on the page is inaccurate, that inaccuracy may appear in the summary, too.
Can I summarize paywall content?
For paywalled content, we can only summarize the text that is visible in your browser.
What languages can be summarized?
For now, page summaries are only to English-speaking Firefox for iOS users. However, support for additional devices and languages will be added in the future.
Who can see what I’m summarizing?
Firefox takes a privacy-preserving approach to summarizing web pages. For iPhone 15 Pro or later users on iOS 26+, we use the on-device Apple Intelligence model to create the summary directly on your phone. For all other users, the web page content is processed on Mozilla-hosted services using the Mistral Small 3.1 model. The summary is sent directly back to your device.
