I also have this issue on Hirsute and 89.0+build2-0ubuntu0.21.04.1

Strangely, in the Gnome overview, all of the firefox windows have
correctly rendered previews, however when you take a screenshot of an
open firefox window, it comes out either blank, or with a transparent
checkerboard pattern. The actual image seen on the monitor is a white
screen.

My workaround for the moment is to downgrade to an older version
sudo apt install firefox=87.0+build3-0ubuntu4

Then launch Firefox once using the command:
firefox -allow-downgrade

And for now I have held the package in apt to prevent upgrades to the broken version:
sudo apt-mark hold firefox
