My setup:
- Windows 10 host OS
- Ubuntu 22.04.1 guest OS running inside VirtualBox 7.0.4
- Several shared host folders auto-mounted on the guest in folder $HOME/Public
- Firefox installed as snap inside the Ubuntu guest OS
Full read/write access to files inside the shared folders works for non-snap applications. Firefox, however, is unable to read/write files in the shared folders. I would like to enable this.
A solution exists for accessing files from other file systems when mounted as removable media in /media and /mnt:
How to access files outside of /home in snap apps?
Another solution describes the use of the --bind option to mount, which allows mounting a file system under one of the accessible directories such as /home, /media or /mnt:
How to give snaps access to /somedir
My use case differs from the above in that I use the shared folder functionality provided by VirtualBox to auto-mount several host OS folders inside $HOME/Public. This auto-mount functionality does not permit (as far as I can tell) the specification of mount options, specifically the --bind option that would probably solve my problem.
In case it's of interest, here are the relevant few lines from the output of snap connections firefox:
Interface Plug Slot Notes
home firefox:home :home -
personal-files firefox:dot-mozilla-firefox :personal-files -
removable-media firefox:removable-media :removable-media -
What is the best way to enable the Firefox snap to access my shared folders without going through extreme contortions?
