HI Michelsouza,
When you execute a test case in katalon, it start a driver instance of browser (not actual browser with all plugins & settings) . It is expected to work this way…
Now if you want to use same active browser then this can be done only with chrome driver in katalon.
For this , follow below steps,
1. Run your test case on chrome browser from katalon studio. (Remove close browser command from test steps.)
2. Now when your execution is complete, your chrome browser will still remain open. To execute test case again on same active browser, select test step (not test case) and right click on it and then click on command “Execute from Here”.
It will execute your scripts on same browser.
