Xmodules Windows Installer, Version 2019-8 on firefox do not work

Here another similar case

For me It’s the same OS and firefox used with old Kantu.

I do not have any recent update of OS it’s the same OS used with old Kantu and Xmodules.

If others users have the same bugs there are a problem in new firefox kantu addons 5.2.3 and xmoduiles 08-2019

Downgrade Kantu and xmodules working all, it’s the latest update of firefox kantu addons and xmodules.

Thanks
