Start browsers in private mode


This is a companion discussion topic for the original entry at


Hey, I just downloaded the new version of Katalon and I am unable to make custom run.

How can I run in private mode with the new version?
If it changed I believe that also the documentation should change


I believe this is now under Desired Capabilities (last option in the list at left).


Hi guys,

What about IE, the configuration for IE is not specified in this post.
Thanks in advance.


IE configuration, you can do in project setting. Please find the below screenshot for more details.


What is the Desired Capability property for IE to start InPrivate mode?


Please make below changes:



is there a way to start in private mode just for one test case? or one test suite? like an option on the script WebUI.openBrowser(’’), as we have to set at project level all tests starts in private mode.

Thank you in advance.


Hi Prabhat
Can you please post the complete property value for this. IE private mode capabilities, thanks.


Hello Pabhat,

Can you please type in here the complete names for the IE and Edge?In the above screen shot they are incomplete. Many Thanks!!



You can use the below property value for IE private mode capabilities:

capabilities.setCapability(InternetExplorerDriver.FORCE_CREATE_PROCESS, true);
capabilities.setCapability(InternetExplorerDriver.IE_SWITCHES, “-private”);


Thanks @sourav.malhotra.cont I tried the same but for Edge changing to “EdgeDriver” but didn’t work. You know how to start on private that browser?


@ [rodrigocalabretta]

For edge you need to set the below capabilities

capabilities.setCapability(“ms:inPrivate”, true);
