Katalon Studio downloads the latest geckodriver (v0.30), but Runtime Engine comes with an older version. (v0.23) I believe. I found an old ticket mentioning why Studio used to use this older version, but it no longer does. So can we get an update to RE please?
Thank you very much for reporting this issue. We will look into it and plan for a fix soon. For now, please use the option -webui.autoUpdateDrivers=true for every run in KRE or manually update your project by using Tools > Update WebDrivers > Firefox.
