Firefox "Ask AI" feature configuration

Did you know that Firefox and Zen (like Arc, but Firefox-based) have an experimental AI query feature?

When enabled, this feature adds an icon next to selected text (optional) and a context menu item - "Ask AI."

By default, it includes a preset list of query types:

• Simplify text
• Create a summary
• Provide detailed explanation
• Generate a quiz based on the text

Interestingly, no API token is required - the chat dialog opens in a sidebar, and since it technically operates as another tab, authentication occurs automatically using your existing browser cookies from previous logins. You only need to select a provider.

To enable:

1. Go to Settings
2. Navigate to Firefox Labs tab
3. Find "AI chatbot" setting

You can also select localhost as a provider by setting browser.ml.chat.hideLocalhost to false in about:config

How to add custom prompts

1. In about:config, create a new parameter with key browser.ml.chat.prompts.x (replace 'x' with any string, avoid numbers as they're reserved for default prompts)
2. Set type as String
3. Enter JSON in the following format:

{
  "label": "Propmpt name",
  "value": "Prompt value"
}

The page title and selected text will be automatically added as a prefix to the prompt, but are also available as variables: %tabTitle% and %selection|12000% where 12000 represents the character limit
