Headless Firefox opens "normal" Firefox GUI

when I try to run my test case with Firefox (headless) it opens and run normal Firefox GUI browser.

It doesn’t matter if I go through Katalon studio or console, testCase, testSuite or testCollection… it’s always the same.

Chrome headless is working as expected (i.e without starting browser GUI).

Please help

I’m having the same issue, any resolution?

Hi @B_L, @Damir_Djordjev
I could not reproduce this problem in Katalon Studio 5.10.1 (Latest Version). I think this may be a problem with the version of your WebDriver. Can you provide us with the log file ?
