Yes, netflix will run in Firefox 47. You may have to install the silverlight plugin, https://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx

I have replaced silverlight 4 times. Netflix still does not run. my mac is a mid 2012 manufacture. would that maybe cause the problem. I am going to return to the previous version of firefox.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> 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 *https://support.mozilla.org/kb/Safe+Mode *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes Firefox 42+ has a Tracking Protection feature that is enabled by default in Private Browsing mode.
