As we reported earlier, on December 17th NetFlix has started offering HTML5 videos for Firefox users. While this not a big deal for the Win32 users as they could still use Silverlight with Firefox, this is not the case for the Firefox Win64 users. The newly released Win64 Firefox browser does not support NPAPI plugins (except Flash).
Note: Silverlight is planned on being supported with the upcoming Win64 version of Firefox 44. However, by the end of 2016 Mozilla plans on removing support for the very outdated NPAPI plugins (except Flash) from Win32 and Win64 versions of Firefox. Google Chrome ended support earlier this year and Microsoft’s new Edge (Windows 10) browser also does not support NPAPI plugins.
