Nope, that did not work. I did both steps twice to double check and still can't stream Netflix. Blah! I guess I will just have to use IE until I can resolve this issue. Thanks for trying...

It's not plugins either. I checked plugins and addons prior to posting. All of them are updated also.

This doesn't work either. I even reinstalled Firefox and I still receive the same error. I give up. This is just silly that I now have to use Internet Explorer to stream videos from Netflix. Your security update screwed up something!!!

The problem is on Netflix's end with their supported user agents. Even though they say that they support any version above Firefox X their support is instead for versions X-5. To remedy the problem until Netflix fixes their code install\use a user agent switcher and create a profile for Firefox version 5
