[Bug 1777070] Re: firefox plugin libwidevinecdm.so crashes due to apparmor denial

[A. Denton]

Solved it for me by editing /etc/apparmor.d/usr.bin.firefox on XSE
(Debian- & Xubutnu 18.04 LTS-based distro):

  # per-user firefox configuration
  #...
  owner @{HOME}/.{firefox,mozilla}/**/gmp-widevinecdm/*/lib*so m,


That solved the problem when using Mz Firefox 100.0 (64-bit) and widevine 4.10.2449.0
