Title:
  [upstream] mozilla cert8.db and key3.db are denied by apparmor

Status in LibreOffice:
  Confirmed
Status in libreoffice package in Ubuntu:
  New

Bug description:
  libreoffice accesses firefox's cert8.db and key3.db, i have found this from 
apparmor log messages.
  i googled "libreoffice cert8.db key3.db" and have found out that seems 
libreoffice does this by design. see 
https://bugs.documentfoundation.org/show_bug.cgi?id=119811 , 
https://weekly-geekly.github.io/articles/357692/index.html . do you agree with 
this? then there should be allow rule, i think. if you do not, then should be a 
comment and / or deny rule.

  does libreoffice really need write access to these files? i think it
  can potentially add some bad certificates, and some sites would have
  verified sign then, while user has not added it to exceptions.

  i think if user have not secured his master password, it can be
  considered it is ok if some app can access his passwords.

  i think this pages also can be helpful:

  -db-file , https://developer.mozilla.org/en-
  US/docs/Mozilla/Projects/NSS/tools/NSS_Tools_certutil , these are
  found by googling "cert8.db key3.db". this also can be helpful:
