AFAIK npapi plugin support has been removed in Firefox 52 so the x2go plugin will not work anymore.

Package: x2goserver

Version: 4.0.1.20-1.el7.x86_64

Package: x2goplugin-provider

Version: 4.1.0.0-1.el7.x86_64

Package: x2goplugin

Version: 4.1.0.0-1.el7.x86_64

All packages are from the official EPEL 7 repository.

When trying to log in using the firefox plugin, the error is:  Failed to connect: Permission denied.  The same credentials work with the x2go client.

I used the example X2Go Demo config file, only changing server=IPaddress.
