I seem to have gotten this working in 14.04 I followed the standard workarounds from http://askubuntu.com/questions/362259/how-to-watch-videos-in-amazon- prime-instant-video
Then I noticed that apparmor was DENYING firefox some access. From syslog: Jun 3 22:54:17 xxxxx kernel: [194199.783739] type=1400 audit(1401850457.516:7270): apparmor="DENIED" operation="file_mmap" profile="/usr/lib/firefox/firefox{,*[^s][^h]}" name="/home/xxxx/.adobe/Flash_Player/NativeCache/xxxxxx/xxxxx/libadobecp-301806-1.so" pid=9145 comm="plugin-containe" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 So I added the following to my /etc/apparmor.d/local/usr.bin.firefox @{HOME}/.adobe/** lrwkm, And it started working. Looks like the 14.04 firefox apparmor profile disrupts Flash DRM. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296705 Title: Amazon Prime Instant Video Does Not Work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/adobe-flashplugin/+bug/1296705/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
