pupeteer-firefox doesn't launch firefox

Steps to reproduce

• Puppeteer version: “puppeteer-firefox”: “^0.5.0”,
• Platform / OS version: macOS Catalina
• Node.js version: v10.12.0

What steps will reproduce the problem?

run the code from example:

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();
})();

example code from https://github.com/puppeteer/puppeteer/tree/master/experimental/puppeteer-firefox

What is the expected result? to launch headless ff and to throw no errors 😃 original puppeteer with chromium works great, but only with sudo

What happens instead?

> sudo node pup
