Hi everyone,
I've installed gucacamole and guacd via Docker. As backend (RDP-desktops) I'm using containers based on this image:
https://hub.docker.com/r/danielguerra/ubuntu-xrdp/
Everything is working fine besides one thing: When I try to stream Firefox as standalone program in an RDP-session without the whole Linux-GUI (guacamole-option "Initial program"), then I cannot open overlay menus like Firefox's "hamburger menu", bookmarks or dropdowns in websites. They are closing again immediately after I click them.
When I stream the whole xfce-desktop and open Firefox in the Linux-GUI, then there is no problem.
Does anyone have an idea what could cause this issue. I already tried out some Firefox-settings like turning of hardware acceleration.
Thanks and best wishes
Michael
