Prime Video: "Your browser does not support High-Definition playback due to content restrictions"

Since 88.0.1 all Amazon Prime Video content displays this message: "Your browser does not support High-Definition playback due to content restrictions. Please update your browser for the best Prime Video experience".

I've tried turning off vpn, adblocker, and set tracking protection back to 'standard', nothing helps.

I'm on W10 1909 Home which is technically not supported by MS as from this week so I did consider that as a possible (but unlikely) reason for it. However, the content plays fine in MS Edge. The content also plays fine from a laptop running Chrome on 1909 Enterprise (similar build to mine albeit not out of support yet).

I see widevine was updated in 88.0.1 - could this be the issue?

Thanks

Soluzione scelta

Resolved. I was about the reinstall and then considered clearing all cookies and data.

Once that was done, content is playing correctly again.

Is it really 88.0.1? It should be fixed in this version.

Yes. I didn't have any issues with 88.0 - content played fine for me.

The bug report for 88.0 seemed to be for bought Amazon content, which I don't have. Maybe the bought stuff is handled slightly differently to the included with Prime stuff that I'm trying to watch.

I can confirm it has nothing to do with 1909 as I've updated to 20H2 and the problem is still there.

Anyway to rollback to a functioning version of Firefox?

This thread is about playing DRM protected HD videos.

If your issue also with DRM or are unprotected videos like on YouTube affected as well ?

YouTube has no problems. I tried also to change DNS to google dns, i was using AdGuard dns, but not even this resolve the issue unfortunately.

I tried also a second instance on Firefox on macOS, without extensions and default settings, but the issue still persists.

more options

So there's nothing to do? If the issue comes with clean Firefox installation too i think there's a problem in the latest version considering working well on Safari. Some times ago there was no issues, but i cannot say when precisely.

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).

"Remove the Cookies" for websites that cause problems:

  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

  • Settings -> Privacy & Security
    Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.
