[apparmor] [Bug 1859361] [NEW] Firefox profile causes widevine DRM to crash

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Tim (tim8816):

Steps to reproduce the issue:
===============================
1) Enable digital rights management support in FireFox (Preferences -> General)
2) sudo aa-enforce /etc/apparmor.d/usr.bin.firefox
3) Navigate to a site which has protected content (I tested this using crunchyroll.com)

FireFox should display a yellow bar at the top letting you know Widevine
has crashed.


Workaround:
===============================
I corrected this problem by adding the following line to usr.bin.firefox:

owner /home/*/.mozilla/firefox/rutsti3o.default-release/gmp-
widevinecdm/4.10.1440.19/libwidevinecdm.so m,


Conclusion:
===============================
Maybe the default FireFox profile can be updated in a way that allows it to play nice with Widevine in the future.
