Description

[niri]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Update to FF 88.0 at 04/23/21 (Even in Save-Mode)

Rollback to FF 87.0 at 04/28/21 (Website full functional)

mozregression: All verdict_b Distributions didn't work, verdict_g Distributions full functional, but no specific Bug-Information.

Actual results:

Amazon.de plays no HD-Movies anymore because the Standards for HDCP aren't giving. Series still playing in HD.

Windows and all FF-PlugIns (OpenH264-Videocodec 1.8.1.1 / Widevine Content 4.10.2209.1) are on latest Update and Error even still up in FF-Save-Mode.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Hi, Bryce,
Could you help me triage this one? It seems related with Widevine update?
Thank you.

Thanks for the report. We're currently rolling out a fix to this issue -- it should be fixed in Firefox Nightly and the most recent beta. We are currently in the process of getting the fix to Firefox release.
