What is included

The current Nirvana build exposes AI-related controls for Page Summaries and translations, and may show other Firefox-derived AI options. Each feature should be checked individually in your installed version. An option’s presence does not mean it is active on every page.

How to review them

Open Settings → AI Controls. Review the global switch, then the entries for Page Summaries and translations. You can keep a useful tool on while turning off another one.

Data and accuracy

Page Summaries can use a cloud provider and can be inaccurate. Translation processing and language packs depend on the installed implementation. Do not assume every AI feature runs entirely on-device; check the feature’s page for its current data path.

Turning a feature off stops future use. It does not delete data already processed.

Your decision

If you do not want AI-assisted page processing, disable the relevant controls. Ordinary browsing, bookmarks and tabs remain available.

What is and is not included

In the current Nirvana build, Page Summaries and Translations are available and have controls. Other Firefox-derived AI entries can vary by region and release; do not assume a third-party chatbot or voice service is included merely because AI Controls exists. Open each entry to see its current status.

Use a feature only when needed

Page Summaries can process readable article text in a cloud service; translations depend on language resources and build behavior. Keep a feature disabled if you do not need it, especially for confidential pages.

Readable page text is sent for processing only when you ask for a summary.

Check a specific page

The control shown in Settings tells you whether a feature is allowed, but it does not guarantee every page is eligible. Region, language, content length, connectivity and release flags can affect whether the action appears.

  • Supported language
  • Content length
  • Region and connection
  • Not a private tab
