Description
When using Arch Linux's profile-sync-daemon (in overlay mode) and running Firefox in firejail, DRM video from Hulu does not play because the WidevineCDM crashes. I've enabled
browser-allow-drmin/etc/firejail/firejail.configand with profile-sync-deamon disabled, it works fine.If I use
ignore noexecwhile using psd, it works fine. So there's something that needs exec permissions. But I don't want an unconditionalignore noexec. I've tried the following infirefox.local, all unsuccessfully (I have a separate Firefox profile for Hulu):In my
globals.localI addedblacklist ${RUNUSER}/*firefox*If I run firejail with debug, with the above noexec lines in
firefox.local, I confusingly still get thisSteps to Reproduce
Expected behavior
Video from Hulu plays
Actual behavior
Widevidecdm crashes
Behavior without a profile
Works perfectly. Even works perfectly with firejail, just not while using profile-sync-daemon
