[RESOLVED] Pbs with movie sites in 24.04

[joneall]

SInce moving to 24.04, I have problems in Firefox with movie sites, Netflix and Prime video. Netflix tells me:

We'\re having trouble playing Netflix. Please make sure you're using the latest version of Firefox and try again.Error code: F7701-1003.

Curiously enough, it's sometimes F7702-1003. They point to a page telling how to install it from a deb file instead apt install. It's fairly messy. It seems to be related to a beast called widevinecdm and DRM. But I have DRM on.

Prime video says:

We're experiencing a problem playing this video.

Only Google Chrome seems to work for these sites..

What to do?

Using Firefox Developer Edition, version 132.0b9 (64-bit).

I got the same message as you after I was signed in to netflix.com. The you must endable DRM message was at the top. I clicked on the link to enable DRM, then the browse page was properly listed and I could click on and play any of the offerings.

Lucky! I don't get that link. I did check and DRM is enabled.

What I do see at the top is simply the message "The WidevineCdm plugin has crashed."

I found the solution to the problem, at least one which works for me.

cd /etc/apparmor.d
sudo cp -p usr.bin.firefox usr.bin.firefox.org
sudo vi /etc/apparmor.d/usr.bin.firefox
​ after "# per-user firefox configuration", add the line
owner @{HOME}/.{firefox,mozilla}/**/gmp-widevinecdm/*/lib*so m,

(the blank before the final "m," is not a mistake, nor the comma!)

After that, you can reboot your computer (or reload AppArmor's rules with

sudo apparmor_parser --replace /etc/apparmor.d/usr.bin.firefox​

Sorry, I thought I had fixed that. Should be good now.
