What works

Everything that this version of Firefox can be expected to do. The browser performs well.

YouTube in 4K performs quite well, and 1080p is perfectly smooth.

What does not


What was not tested

Probably many things. I did not install Flash to test that.

Additional Comments

Out of the box on Wine 4.9, HTML5Test gives Firefox 49.0.2 (both 32-bit and 64-bit) a 463 out of 555 possible points.

Sometimes the tabs appear underneath the window title bar, and sometimes with distorted background coloring, but this issue goes away if you simply resize the window.
