Re-triaging per https://bugzilla.mozilla.org/show_bug.cgi?id=1473195 Needinfo :susheel if you think this bug should be re-triaged.

Karl, is this also a bug affected by the Chrome behavior change just like bug 1064982? I mean we can close this too?

Hiro, It seems this is now working the same in both Firefox and Chrome. I think we can close. If you go to https://bokand.github.io/demo/urlbarsize.html You will noticed just two small differences that might be worth investigating. 1. When scrolling up the two orange bars have different sizes in Chrome, same sizes in Firefox 2. There is a kind of jankiness when scrolling on Firefox when the two orange bars becomes suddenly longer (I guess when the URL bar is hidding).

I think that's because the window.innerHeight is expanded when the URL is hiding. And I think it's reasonable.
