I wanted to add that I am seeing this problem - however, Netflix initially worked fine for about a month.
My current Firefox version is 53.0.3 32-bit. I do not know if this is the version that was installed with Ubuntu Mate (16.04 LTS), or if I was updated to 53.0.3. (and if it was an update, I don't know when it occurred - I'm new at linux, and the logging I was able to find in Firefox did not show any updates). Netflix was working, I left the machine for a while and was logged out. When I came back, I received the error. No amount of disabling extensions, restarting, logging out/in, and cache clearing has had any effect. Luckily, I have another machine I can use to watch, but I hope someone is able to fix this soon. If anyone would like further information from me, I am happy to help, but I will need instructions on how to get the information you want. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685104 Title: Netflix returns error F7363-1260 as movie loads.
