To help personalize your experience in Smart Window and make assistant responses more helpful over time, Firefox can learn from your activity to create short summaries called memories.

Memories are optional, and you can choose which activity is used to create them.

How memories are created

Memories are created based on two possible sources of local information:

• Browsing history in Classic and Smart Windows
• Chats in Smart Window

In Firefox Settings, you can choose to have memories created based on either or both of these sources.

First-time setup

When you use Smart Window, Firefox may create initial memories using your recent activity. This includes up to 60 days of browsing data or 3,000 items, whichever limit is reached first.

Memories are stored locally on your device and can be deleted at any time. Also, the data is not accessible to Mozilla.

To generate memories, Mozilla servers briefly process this data, but it is not stored or logged beyond what is needed to complete the request.

How memories are updated

Memories are updated automatically in the background when meaningful new activity is detected. Updates may happen when:

• You visit at least 30 new pages since the last update
• There are at least 10 visits within 60 days and a noticeable change in browsing activity (for example, exploring new topics)
• You send at least 10 new messages in Smart Window

If Smart Window is closed, memory updates pause. When you return, any browsing activity during that time may be used to create new memories once Smart Window is active again.

Examples of memories

If you spend time viewing vegan recipes and vegan restaurants, Firefox might create a memory like “Prefers vegan recipes and cuisine”. Memories will always be personal. Here are some hypothetical examples of memories:

• Researches local hiking trails
• Uses Python and C++ tutorials
• Follows WNBA league standings
• Edits emails to sound professional
• Plans trips to Austin

How we preserve your privacy

To create memories, your browsing and chat history are sent to a Mozilla server for processing. Memories are then returned and stored locally, on your device so only you can see them. Other important points:

• Mozilla does not retain any of this data on its servers after processing.
• Memories are only used to help personalize the Smart Window experience: Mozilla does not sell your data to advertisers.
• We have filters in place to help prevent memories on sensitive topics like health, finance, and legal.

How memories are used

Memories are used as context to help personalize assistant responses in Smart Window.

When you chat, the assistant queries your memories to see if there’s anything relevant that could be used to help personalize your response. For example, if you have a memory like “Prefers vegan recipes and cuisine”, if you ask the assistant “recommend a recipe for dinner,” the answer will likely be personalized with vegan options, instead of providing general ideas.

When a response uses memories:

• You’ll see the memories icon below the response.
• Select the icon to see a small pop-up which lists the memories used. If you see a memory that doesn’t seem quite right, you can delete it.
• Select Retry without memories for a non-personalized response.

Turn off memories for a single chat session

You can disable memories for a specific conversation for a non-personalized response.

1. In the assistant entry box, find the memories icon.
2. Turn the memories toggle off for that chat.
3. Continue your conversation.

How to control and manage your memories

View and delete memories

You can see all your memories at any time in Settings.

1. Go to AI controls.
2. Select Smart Window.
3. Select Manage memories to view your memories.

From the Manage memories page, you can delete individual memories or delete them all. Select the trash icon next to any individual memory to delete it. Or, select the Delete all button to delete all memories.

Change what activity Smart Window learns from

Memories are created based on two possible sources of activity:

• Browsing activity in Classic and Smart Windows
• Chat activity in Smart Window

You can change what Smart Window learns from at any time in Settings.

• Go to AI controls
• Select Smart Window
• Under Memories choose what activity you want Smart Window to learn from.

Stop new memories from being created

If you don’t want memories created anymore, turn off both learning from browsing and chat activity in Settings.

1. Select AI controls.
2. Select Smart Window settings.
3. Under Memories, uncheck:
   • Learn from browsing activity.
   • Learn from chat activity.

FAQs

If I delete my history and chats, are my memories deleted too?

No. Memories are stored separately from browsing history and chat history. If you want to remove memories, delete them from Settings > AI controls > Smart Window > Manage memories.There, you can delete individual memories, or delete all of your memories.

Can I ask for specific memories to be created?

Right now, no. The assistant in Smart Window can’t create memories based on you asking. The assistant may be able to remember things you tell it to, for the duration of a single chat, but it won’t be able to create a memory based on you requesting it.

Are memories synced across devices?

Right now, no. Memories cannot be synced across devices.
