Different work of headless mode

[lusy777]

I noticed different work when I'm calling $browserFactory->createBrowser() with/without 'headless' => false
With 'headless' => false appeared chrome window with load page and return full html page, but without this option I see in html response "..You don't have permission to access.. "
I thought both modes were supposed to work the same?

Probably the website is identifying the headless mode and changing its behaviour.

Is there any trick to fool this identifying?

You can try tweaking the things that this tool checks for to detect headless: https://github.com/infosimples/detect-headless
