I have Firefox 13.0.1 installed (also tried the beta, 14 or whatever) and I can't play movies on Netflix. Silverlight is up-to-date, everything is up-to-date, but it doesn't work. It goes to that page that says,
"Complete System Requirements
To watch instantly, youll need a computer that meets the following minimum requirements:
Windows XP with Service Pack 2, Vista or Windows 7
Internet Explorer 6.0 or higher; or Firefox 3 or higher; or Chrome 7 or higher
1.2 GHz processor
512 MB RAM
An Intel-based Mac with OS 10.4.11 or later
Safari 3 or higher; or Firefox 3 or higher; or Chrome 10 or higher
1 GB RAM
A Google Chromebook with Chrome OS 13 or higher"
But if I open and try it in Google Chrome, it goes just fine. I'm on Windows 8 Release Preview, and it's a 64bit system. Firefox is 32bit, of course. I don't know what else I can possibly try to get Netflix to work in Firefox. Chrome is fine, but Firefox is my default browser, and I wish I didn't have to switch over every time just for Netflix.
Thanks, Paddingtonbear, that did it. Although it seems ridiculous (considering I have the SAME EXACT setup on my laptop, Windows 8, 64 bit, everything and it worked fine) the addon solution works like a charm on my desktop. Thanks a lot!
