Enabling DRM on Firefox
How do I enable DRM on my Firefox browser?

If you go into the Firefox settings in the Content tab, there should be a Play DRM content checkbox that allows you to enable DRM on Firefox.
Admittedly, I'm not sure if it will still work properly for you, given that you are on a very old version of Firefox because you are still on Windows Vista. I'm not sure if the Google Widevine software still installs properly automatically on that version of Firefox.
You may need to press the menu button in Firefox, select Add-ons and then select Plugins from the left side to manually enable Google Widevine in the list of plugins.
Hope this helps.
