Firefox has different summary features on desktop and mobile. On desktop, block the relevant feature in Settings (or Preferences) > AI Controls. On Android, go to Menu > Settings > Page summaries and turn off Summarize pages. If a summary is already covering a page, use any visible in-app back or close control; Mozilla’s instructions do not specify a universal way to restore the exact prior view.

First identify which Firefox summary you’re seeing

The right setting depends on where the summary appears. A short set of key points shown when you press or hold a link on desktop is a link-preview feature. Android’s Page summaries create a summary of an eligible webpage, while Shake to Summarize is a gesture that opens that mobile feature. Mozilla documents mobile AI controls for iOS where available, but availability and controls can vary by device and location.

  • Desktop link preview: Block the link-preview feature in AI Controls.
  • Android page summary: Turn off Summarize pages in Page summaries settings.
  • Android shake gesture: Turn off Shake to summarize separately.
  • iOS: Shake to Summarize may be available; consult the controls shown in your version of Firefox rather than relying on a universal menu path.

Turn off summaries in Firefox on desktop

Mozilla’s desktop instructions, dated February 24, 2026, place the controls in Firefox Settings or Preferences. The global control blocks AI enhancements, while individual controls let you block a particular feature such as link-preview key points.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Open Firefox Settings (or Preferences).
  2. Select AI Controls.
  3. To block current and future AI-enhanced features, turn on Block AI enhancements. To keep other features available, find the relevant feature’s dropdown and set it to Blocked.

Mozilla describes AI Controls as covering newer AI-enhanced features, including translations, PDF image alt text, tab-group suggestions, link-preview key points, and the sidebar chatbot. It is not a switch for every use of machine learning in Firefox: traditional classification, ranking, and personalization are outside this panel, and some features are controlled by third parties. See Mozilla’s desktop AI Controls guide and Firefox Support’s AI Controls article.

Turn off Page summaries or the shake gesture on Android

  1. Open Firefox’s three-dot menu and tap Settings.
  2. Tap Page summaries.
  3. Turn off Summarize pages to stop generating page summaries. If you only want to prevent the gesture, leave summaries enabled and turn off Shake to summarize.

These are separate controls. When summaries remain enabled, Mozilla says the toolbar button can be used instead of shaking. Mozilla’s Android Page summaries instructions say the feature works on webpages readable in Reader View and shorter than 5,000 words. Availability is worldwide for English-based webpages; very long or unsupported pages may not offer the option. Mozilla lists news articles, how-to guides, reviews, recipes, research articles, and opinion pieces as examples of eligible content.

Restore the original page if a summary is already open

Turning off a feature prevents or blocks its use; it does not necessarily dismiss a summary that is already on screen. Mozilla’s cited instructions do not document a specific command that closes an open summary and returns to the exact previous page state. If one is covering the page, use a visible in-app back or close control if present. The available control and result may depend on your Firefox version and screen.

What to know about summary accuracy and processing

Mozilla warns that summaries may be inaccurate and advises checking important details against the original page. On Android, the support article describes summaries as using a Firefox AI cloud-based solution powered by Mistral Small 3.1. It also says summaries are unavailable in Private Mode, supported summary language is currently English, and only visible content is included for paywalled pages.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Processing can vary by device and operating system. Mozilla’s Firefox Privacy Notice says that, on compatible devices with a supported operating system enabling on-device intelligence, requested Shake to Summarize summaries are created locally. Otherwise, page content is sent to a Mozilla server for processing and returned to the device. Mozilla says it does not store the content or resulting summaries; the local-processing path should not be assumed for every device.
