1304899 - [EME] Don't download Adobe Primetime CDM by default

Status: VERIFIED FIXED

(Core :: Audio/Video: Playback, defect, P3)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

We should disable the Primetime CDM so that it isn't downloaded and installed by default. We still want to leave it "visible", so that it will appear disabled in the addons#plugins UI, and the user will be prompted to enable it if a site is encountered which tries to use Adobe Primetime EME.

Attachment: Bug 1304899 - Don't download Adobe Primetime CDM by default.

Disabling the Adobe CDM but leaving it visible means that we won't download it
and if a site tries to use it we will prompt the user to enable DRM and only
then download it.

I've reproduced the issue described in comment 0 using 52.0a1 old Nightly (Build Id: 20160922030437) and verified that the issues is fixed using Firefox 52.0a1 old Nightly (Build ID:20160927030200)after the patch landed, across platforms (macOS 10.12 and Windows 10 64bit). 

However I have noticed that on Firefox 52 beta 8 ( Build ID:20170220070057) Adobe Primetime CDM is not visible in the about:plugins and about:addons pages. 

Could you please tell me if Adobe Primetime CDM is included in the Widevine Content Decryption Module provided by Google Inc?

We removed Adobe Primetime from Firefox in 52. What you're seeing is expected.

Thank you Chris!
Based on my testing and comment 7 I think it’s safe to mark this as verified fixed since I already verified that the issue does not reproduce on a build after the patch landed Nightly 52.0a1(Build Id:20160927030200)even though in today's 52 beta 8 (Build Id:20170220070057) Adobe Primetime is completely removed.
