What is not working? I have been using google flights to book trips for months without issues now. The only google services I've had some trouble with firefox are hangouts, and even that is fixed.

Try it on Android, where Google controls more of the market, and has less incentive for interop. You get a door slammed in your face: https://twitter.com/andrewhobden/status/1007668509826928640

Great response from Alex Russell, but it's clear that the sentiments of the Chrome team aren't translating into policy elsewhere in Google, or we wouldn't be dealing with something like this every few months.

Oh wow, I never noticed this before, this must be a recent thing...Thanks!
