# Puppeteer for Firefox

> Use Puppeteer's API with Firefox

> **BEWARE**: This project is experimental. 🐊 live here.

## Getting Started

### Installation

To use Puppeteer with Firefox in your project, run:

```bash
npm i puppeteer-firefox
# or "yarn add puppeteer-firefox"
```

Note: When you install puppeteer-firefox, it downloads a [custom-built Firefox](https://github.com/GoogleChrome/puppeteer/tree/master/experimental/juggler) (Firefox/63.0.4) that is guaranteed to work with the API.

### Usage

**Example** - navigating to https://example.com and saving a screenshot as *example.png*:

Save file as **example.js**

```js
const pptrFirefox = require('puppeteer-firefox');

(async () => {
  const browser = await pptrFirefox.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'example.png'});
  await browser.close();
})();
```

Execute script on the command line

```bash
node example.js
```


### API Status

Big lacking parts:

- `page.emulate`
- `page.pdf`
- all network-related APIs: `page.on('request')`, `page.on('response')`, and request interception
