Torbrower no longer asks where to download even though that option is
enabled in its settings.

Torbrowser no longer can download a file to my home directory ("Could
not read the contents of ...)". I get impression that apparmor is
preventing a download to where I want. So I put the line:

owner "@{HOME/" rw,

into /etc/apparmor.d/torbrowser.Tor.tor . This has no effect.

I also ran to no effect:
$ sudo sh -c 'echo "owner /dev/shm/wayland.mozilla.ipc.[0-9]* rw," > /etc/apparmor.d/local/torbrowser.Browser.firefox ; apparmor_parser -r /etc/apparmor.d/torbrowser.Browser.firefox'

The package apparmor-profile-torbrowser is not in Chimaera rspository.
