# Puppeteer-Firefox > Puppeteer-Firefox - Puppeteer API for Firefox > **BEWARE**: This project is experimental. Alligators live here. ## Getting Started ### Installation To use Puppeteer-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) 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 - class: Puppeteer * puppeteer.executablePath() * puppeteer.launch([options]) - class: Browser * event: 'targetchanged' * event: 'targetcreated' * event: 'targetdestroyed' * browser.close() * browser.newPage() * browser.pages() * browser.process() * browser.targets() * browser.userAgent() * browser.version() * browser.waitForTarget(predicate[, options]) - class: Target * target.browser() * target.page() * target.type() * target.url() - class: Page * event: 'close' * event: 'console' * event: 'dialog' * event: 'domcontentloaded' * event: 'frameattached' * event: 'framedetached' * event: 'framenavigated' * event: 'load' * event: 'pageerror' * page.$(selector) * page.$$(selector) * page.$$eval(selector, pageFunction[, ...args]) * page.$eval(selector, pageFunction[, ...args]) * page.$x(expression) * page.addScriptTag(options) * page.addStyleTag(options) * page.browser() * page.click(selector[, options]) * page.close(options) * page.content() * page.evaluate(pageFunction, ...args) * page.evaluateOnNewDocument(pageFunction, ...args) * page.focus(selector) * page.frames() * page.goBack(options) * page.goForward(options) * page.goto(url, options) * page.hover(selector) * page.isClosed() * page.keyboard * page.mainFrame() * page.mouse * page.reload(options) * page.screenshot([options]) * page.select(selector, ...values) * page.setContent(html) * page.setViewport(viewport) * page.target() * page.title() * page.type(selector, text[, options]) * page.url() * page.viewport() * page.waitFor(selectorOrFunctionOrTimeout[, options[, ...args]]) * page.waitForFunction(pageFunction[, options[, ...args]]) * page.waitForNavigation(options) * page.waitForSelector(selector[, options]) * page.waitForXPath(xpath[, options]) - class: Frame * frame.$(selector) * frame.$$(selector) * frame.$$eval(selector, pageFunction[, ...args]) * frame.$eval(selector, pageFunction[, ...args]) * frame.$x(expression) * frame.addScriptTag(options) * frame.addStyleTag(options) * frame.childFrames() * frame.click(selector[, options]) * frame.content() * frame.evaluate(pageFunction, ...args) * frame.focus(selector) * frame.hover(selector) * frame.isDetached() * frame.name() * frame.parentFrame() * frame.select(selector, ...values) * frame.setContent(html) * frame.title() * frame.type(selector, text[, options]) * frame.url() * frame.waitFor(selectorOrFunctionOrTimeout[, options[, ...args]]) * frame.waitForFunction(pageFunction[, options[, ...args]]) * frame.waitForSelector(selector[, options]) * frame.waitForXPath(xpath[, options]) - class: JSHandle * jsHandle.asElement() * jsHandle.dispose() * jsHandle.getProperties() * jsHandle.getProperty(propertyName) * jsHandle.jsonValue() * jsHandle.toString() - class: ElementHandle * elementHandle.$(selector) * elementHandle.$$(selector) * elementHandle.$$eval(selector, pageFunction, ...args) * elementHandle.$eval(selector, pageFunction, ...args) * elementHandle.$x(expression) * elementHandle.boundingBox() * elementHandle.click([options]) * elementHandle.dispose() * elementHandle.focus() * elementHandle.hover() * elementHandle.isIntersectingViewport() * elementHandle.press(key[, options]) * elementHandle.screenshot([options]) * elementHandle.type(text[, options]) - class: Keyboard * keyboard.down(key[, options]) * keyboard.press(key[, options]) * keyboard.sendCharacter(char) * keyboard.type(text, options) * keyboard.up(key) - class: Mouse * mouse.click(x, y, [options]) * mouse.down([options]) * mouse.move(x, y, [options]) * mouse.up([options]) - class: Dialog * dialog.accept([promptText]) * dialog.defaultValue() * dialog.dismiss() * dialog.message() * dialog.type() - class: ConsoleMessage * consoleMessage.args() * consoleMessage.text() * consoleMessage.type() - class: TimeoutError Special thanks to [Amine Zaza](https://bitbucket.org/aminerop/) who volunteered the [`puppeteer-firefox`](https://www.npmjs.com/package/puppeteer-firefox) NPM package.
