In the past, Netflix would not work in Linux without jumping through hoops. About a year ago or so, Netflix added support for Chrome under Linux. This worked fine with no extra steps required.
Today, however, I loaded up Netflix for the first time in a while and the web page was broken. Missing links, text that should have been links, missing graphics–totally unusable. A little Googling turned up that some extensions can break Netflix. AdBlock is one of them. The solution is to whitelist netflix.com in the extension. Unfortunately, I had already done that. The next step is to disable extensions one at a time to find the guilty party. This time it was Privacy Badger. Luckily, it has a domain whitelist setting also. Adding www.netflix.com fixed the problem.
