Katalon Recorder won't record

Am trying to use the Katalon Recorder (Selenium IDE for FF55+) and it’s not recording any keystrokes. I’m Katalon Recorder IDE 3.4.10 and Firefox 60.2. Have also tried Katalon Studio 5.7.1 to record but my web application requires an X509 certificate and I can’t make that work. In the old Selenium IDE, we created a profile for Selenium and added the required certificates to the profile. Help with either or both would be greatly appreciated.

I am using Katalon Studio version 5.10.1.W hen I click on "Record Web " it is appearing error msg.

Below are error msg and screenshot

“Cannot generate test steps”
