If you don't spend any time on Nightly in Windows 10, please feel free to

tl;dr: we're sometimes creating the first window differently than usual,
so
be on the lookout for breakages.
On 2021-01-05, a change landed in Nightly which enabled the pre-XUL
skeleton
UI [1]. This is a feature which allows us to create the first window and
populate it with a non-interactive placeholder UI before we load
xul.dll. On
some systems, this can mean we can give visual indication of Firefox
launching as much as 15 seconds sooner than normal (loading xul.dll can
take
a while). We're hoping this could be a big win for users who experience
very
slow startups, and we also hope it will improve the overall snappiness of
startup even on fast systems.
What does the placeholder UI look like?
Colors and layout can vary, but the basic look is this:
