Given that something like Furius ISO Mount installs Nautilus and other stuff in Xfce, what would be more recommendable in Xubuntu?
It seems that a such application must have some level of integration with the File Manger, in this case Thunar.
Having a context menu "mount" option in Thunar for iso files like we have for partitions would be great. Maybe through Thunar custom actions?
I used AcetoneISO in the past with Xubuntu 12.04 and 12.10. Does it work ok in 14.04? I read here, that it works bad with 13.04 (French text: Il semble que sous Ubuntu 13.04 le logiciel fonctionne mal.)
EDIT after comment @Bill:
I do not know why I cannot make work a custom action in Thunar 1.6.3 with the command provided at the link help.ubuntu.com/community/ThunarCustomActions
gksudo mount -o loop -t iso9660 %f /mnt'
I have created a custom action with that command, made it visible in the context menu by making settings similar to those presented in my answer below, but I don't see any mounted device in Thunar's left panel.
