If kernel is compiled with CONFIG_SECCOMP=n, the Widevine plugin that is automatically installed with firefox-bin fails to provide a CDM licence when trying to play content protected by DRM. Recompiling the kernel with CONFIG_SECCOMP=y fixes the problem. Maybe the ebuild could check for the option and issue a warning it SECCOMP is disabled.
I recall helping a user with that issue ~2 years ago but I didn't think to report it, I guess it's still happening (should apply to non-bin as well). It was kind of hard to figure out without a check.
