Mozilla not launching


I’m new in using Katalon trying to record a script using Mozilla firefox , but that’s not opening and when i try to run any recorded script using Mozilla giving me error “ failed to connect to localhost 0:0:0:0:0:0:0:1:49112…”
Katalon Version:7.1.0.
Mozilla version:68.5
Windows 10

Do i need to do any addition config setting in Mozilla or in Katalon in order to work with Mozilla.

Please help.


I suggest you upgrade your Firefox to the latest version (76.0.1 at the time of writing). I’d also suggest you upgrade your Katalon too – Click on the Free Download link at the top of this page.
