# Prototype: Puppeteer for Firefox

> Use Puppeteer's API with Firefox

**⚠️ BEWARE**: Experimental. Just for preview. Installation and usage will change.

This project is a feasibility prototype to guide the work of implementing Puppeteer endpoints into Firefox's code base. Mozilla's [bug 1545057](https://bugzilla.mozilla.org/show_bug.cgi?id=1545057) tracks the initial milestone, which will be based on a CDP-based [remote protocol](https://wiki.mozilla.org/Remote).

## Getting Started

### Installation

To try out 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/puppeteer/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
```
