Killed by Mozilla
As of version 56 (currently in Beta), Firefox supports running headlessly on Windows, macOS, and Linux. Brendan Dahl has previously described how to use SlimerJS to drive headless Firefox . You can also drive it via the W3C WebDriver API , and this blog post explains how to do that in Node.js with the selenium-webdriver package.
(For a similar introduction using Python on Windows, see Andre Perunicic’s Using Selenium with Headless Firefox .)
First, ensure you have a version of Firefox that supports headless. On Linux, the current release version (55) is sufficient. On Windows and macOS, however, you’ll need at least version 56, which is currently in Beta (scheduled for release next month). You can also use Developer Edition (based on Beta) or a Nightly build; any pre-release build will do.
