Whenever I play a video on amazon prime thru FF 88 it is SD. When I go to the options for video it says HD is unavailable even if best is selected. When the video first plays the HD icon will come up for about a second, but faded, than go away right after. Usually when it does that it becomes solid white and shows HD at 1080. I'm using Win 10 64-bit Pro 20H2.

When I try watching the same videos in Chrome I have no issues and the content plays fine in HD 1080p.

I tried removing all history, refreshing FF, uninstalling and re-installing my NVIDIA drivers but same issue. I am on 88.0. No add ons or themes. Just default FF after refresh. Nothing helps.

I have seen other reports of widevine crashing but I dont have that issue. FF just wont play Amazon video in HD anymore.

Edit:

After trying some things and completely uninstalling firefox from system and all folders I finally got Amazon to play HD 1080p content again, but only a short while.

For some reason on refreshed or completely new installs of FF 88 amazon would have issues and only play SD. Even if all folders were deleted before install. When I installed the previous version of FF to 87 content was once again playing back at HD 1080p. I than updated to 88 and it was ok but only for a bit.

Even though FF 87 installed and updated widevine, FF version 88 would update it again a short while later but the version numbers of widevine (4.10.2209.1) stayed the same. Whatever version 88 is doing to widevine it seems to cause a conflict preventing Amazon from playing videos in HD content.

Edit 2:

From my other computer which had not updated to 88 yet had widevine version 4.10.1582. I took all those files and replaced the ones in the folder for 4.10.2209.1. I have updates disabled for widevine now and Amazon is playing HD 1080p once again with no issues. So whatever the update did with widevine it is definitely causing a conflict with playing back HD 1080p content on Amazon Prime video.

Widevine will revoke Widevine Content Decryption Module which is earlier than ver 4.10.2209.0. https://www.widevine.com/news

Google has already released new version of CDM. However, the version on Firefox 88.0b7 is still 4.10.1582.2. You can check on the following menu: [Add-ons and Themes]>[Plugin]>[Widevine Content Decryption Module]

My questions are: 1. When is new Widevine CDM coming to Firefox? 1. Can Add-on Manger provide this update to older Firefox?
