How to open FireFox in private browsing mode

How can we open firefox in private browsing mode with Katalon. (I know how to do it for chrome, but I am not able to figure out how to make it work for Firefox.)

It’s going to be something in Desired Capabilities

I wish someone would explain how to set a Firefox profiles (there’s an old message on this forum I saw that talks about the profile setting being a dictionary, but nothing about the key and value it expects).


any solution?

Start browsers in private mode
Open Project -> Settings.
Select Desired Capabilities -> Web UI -> Firefox.
Add a new property named firefox_profile with dictionary type and browser. privatebrowsing. autostart=true as its value.
