need a bigger sample size really. 14% of reddeet.coms 12 active users is 1 person

14% ain’t bad i suppose. and some FF users may be masking, and your sample size of 12 may not be very representative

if your updates included a new kernel try installing the kernel headers for the new kernel.

then if it’s still not working reinstall the nvidia driver.

i used to daily drive debian with proprietary nvidia drivers and it would break with every kernel upgrade

from memory, so almost certainly incorrect, the fix was simply something like

sudo apt install linux-headers-`uname -r` && sudo reboot

have any instance admins ever shared the browser stats?
