Hello. I'm unable to stream Netflix using Firefox (version 56.0.1). First time user of Netflix.

I've checked all the steps on their help page https://help.netflix.com/en/node/32661 and everything looks right.

Shockwave Flash 27.0 r0 and Widevine Content Decryption Module 1.4.8.1008 are both up to date and always active.

My personal computer is running windows 8.1.

Can anyone help please?

Thank you.

Try to toggle DRM off/on to see if that makes Firefox (re)load DRM components.


If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin) always make sure such extensions do not block (wanted) content.

  • make sure your extensions and filters are updated to the latest version

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

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