A few months back, I wrote a popular article called Making Chrome Headless Undetectable in response to one called Detecting Chrome Headless by Antione Vastel. The one thing that I was really trying to get across in writing that is that blocking site visitors based on browser fingerprinting is an extremely user-hostile practice. There are simply so many variations in browser configurations that you
Since Firefox 57, the --screenshot flag allows you to take screenshots of websites. The basic usage is as follows: /path/to/firefox -P my-profile -headless --screenshot https://developer.mozilla.org/ This creates a full-height screenshot of https://developer.mozilla.com/en-US/ called screenshot.png, in the active directory, with a viewport width of 800px. You can omit -headless when using --screen

I am currently testing a new detection technique, feel free to challenge it and give me some feedback. Whatâs a headless browser?

These days, when the phrase "headless browser" is mentioned, you immediately think of PhantomJS, but - there are alternatives.

PhantomJS is great tool and is widely used by companies and developers around th
