>At the moment we recommend granting the capability in the profile and
letting firefox setup its sandbox.
why do not ubuntu developers add it? (before they make it other way.)
>Unfortunately this means you can't guarantee the rest of the program
isn't doing things it shouldn't.
what it can do
i have some questions and wishes about rules that are in the profile:
# so browsing directories works
/ r,
/**/ r,
what if comment these out and allow / and owner @{HOME}/** , instead of
these? does firefox need other directory listings? maybe i will try.
i see /usr/ r, /etc/ r, /opt/ r,
what is ubuntu's policy for updating this profile? it looks like package
maintainers are not updating this profile on every package update. why?

libreoffice accesses firefox's cert8.db and key3.db, i have found this from

i googled "libreoffice cert8.db key3.db" and have found out that seems
libreoffice does this by design. see

i think that that means that apparmor profile lags behind libreoffice
and should be updated.
if it is by design, than there could be comments about that, and it is
possible to remove the logs by "deny" keywords.
that messages are bad because they use space in syslog making it harder
to read, and
