I ranted about this on Twitter, @ah3rz advised me about these forums, so here goes, hoping the team sees it. Strong language ahead, I was (and still am) fairly upset.
Browser is Firefox, latest, on Arch Linux. Flash is not available, JS runs fine (I don't have noscript), I do have uBlock enabled with the default lists. Firefox's Tracking Protection doesn't detect (and block) anything. In the console, I see a bunch of HSTS errors, but it doesn't seem to be be affecting behaviour:
Strict-Transport-Security: The site specified a header that could not be parsed successfully.
Background: I use Docker Cloud both for managing my personal services (blog, various websites, irc bouncer, etc) and at work, for production and staging services, as well as a few ops tools. We have several dozen services across three nodes total, and probably will be doubling that in the next year. Not big, but not tiny, either.
