puppeteer/experimental/puppeteer-firefox/test/waittask.spec.js
Andrey Lushnikov 45ab3e0332
feat: introduce puppeteer-firefox (#3628) 
This adds a proof-of-concept of `puppeteer-firefox`.
This consists of two parts:
- `//experimental/juggler` - patches to apply to Firefox.
- `//experimental/puppeteer-firefox` - front-end code to
be merged with Puppeteer.

As things become more stable, we'll gradually move it out of
the experimental folder.
