I had been using firefox 49 on Ubuntu 14.04, 64-bit,
with the user agent solution found here, and all was well:
Now that I have Firefox 49 or higher, how do I watch Netflix?
Then firefox 50 came along and now I get this message at the top of the browser window:
"libavcodec may be vulnerable or is not supported and should be updated to play video"
And netflix tells me:
"Whoops, something went wrong…
Netflix Video Player Unavailable
We're having trouble playing Netflix on your browser. Please make sure you are on an official version of Chrome.
Error Code: M7355-1204"
I have tried searching for the libvacodec error and for firefox 50 + netflix. Anyone have a solution to this?

Ubuntu Modifications 3.2 is causing the problem! If you are using Ubuntu (any flavor) and are using Firefox as a search engine go into Add-ons manager then into Extensions and disable or remove Ubuntu Modifications 3.2! Restart Firefox ------ Linux Is Great :-)
