See the attached video, comparing start-up times of Firefox Nightly with Google Chrome on the 2018 reference device.
We're consistently faster to paint the first frame, as well as the browser UI. The major deficit seems to be the painting of the initial frame of about:home.
The video shows us waiting for about 7 seconds from browser UI paint to first frame of about:home. I'd like to get this to 4 or fewer seconds.

Just saw in the profile from comment 1 that there's time spent loading FormAutofillContent.jsm and the data: URI process script that was used to load it, which should all be gone with bug 1474143
Depends on: 1474143
