I tried to watch Netflix on your browser but got the error message above with a statement along the lines that I needed to install the latest update of firefox.

"It means that the version of Mozilla Firefox you're using on your computer is no longer supported. Follow these steps to fix the problem."

I did update and restarted the browser and later my computer, the same message is appearing.

Hmmm. Your User Agent looks okay to me: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0


Websites say that Firefox is outdated or incompatible even though it's the latest version

You can check out at the browserspy website how websites see you:

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem,

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

While you are in Troubleshoot(Safe) mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Make sure you have the latest Widevine plugin installed.

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

You can possibly check the XHR requests in the Browser Console if this doesn't work.

Hi rangikudoug, did this help:

Make sure you have the latest Widevine plugin installed. Try to toggle DRM off/on to see if that makes Firefox (re)load DRM components.

As background, Firefox uses the Widevine plugin to work with DRM (copy protected) media. The error message could be a problem with using either a too-old or a too-new version of Widevine. Since Firefox normally updates Widevine automatically in the background, this problem may go away on its own, but we are looking for leads on how to speed that up so we can share them in all the new Netflix threads.
