[Message part 1 (text/plain, inline)]

One possibility is that you're seeing the virtual root filesystem, that thwuld only have a few direccories and the structure up to the directory you created your container in. Are you sure you can access files outside of the directory you started icecat in?

Another possiblity is that you had a running icecat outside of the container. In that case, calling icecat from tge container only opens a new window in the un-containerized icecat. Could it be what's happening?
