Netflix caps video quality at 720p for Chrome and Firefox users

Netflix supports 1080p playback on Safari and Microsoft Edge, but discreetly caps every other browser at 720p. 

You can test this yourself with Netflix's test pattern.

There aren't any options to change this, even if you're paying for 1080p. Fortunately, there is a Chrome/Firefox extension which bypasses it.
