# Install for Firefox

### Firefox

Visit the link below to download **Keeper Password Manager & Digital Vault** from Firefox Browser Add-ons.

{% embed url="<https://addons.mozilla.org/en-US/firefox/addon/keeper-password-manager/?utm_content=search&utm_medium=referral&utm_source=addons.mozilla.org>" %}

Once installed, the Keeper icon shows when you click the puzzle on the top right of the Firefox browser window.

Next we recommend you disable your browser's built-in password saving features:

1. In the upper right corner of your browser click on the **Menu Icon** (3 horizontal lines) and select **Settings > Privacy & Security**.
2. Under "Logins and Passwords", uncheck the box next to "Ask to save logins and passwords for websites".

To ensure you are using the latest version of KeeperFill and allow Keeper to run in private windows, enable both of these settings (pictured below) from the Keeper extension menu. Right-click on the Keeper extension icon in the upper-right corner of your browser window and select "Manager Extension".

{% hint style="info" %}
Private mode on Firefox only currently works if you login from the Web Vault. Logging in directly from the browser extension will not login to Keeper.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/user-guides/browser-extensions/keeperfill-for-firefox.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
