boot up after 'sleep' mode

my new monitor offers a screen where I can shut down, sleep, or restart.......I usually chose sleep, because I think it allows me quicker access to my browzer home page when moving the mouse for reboot. However, about six or more times now, the sleep mode will stop, a "don't interrupt" message in ghost script in the upper left hand corner of the screen comes on, the an HP logo with a dizzing circular moving gif suggest the computer is starting........no so. I have waited 30 minutes or more, started and stopped with the power button, hit every key on the board and swear prolifically now and then with NO results. Using a fairly new HP computer, win 11, and version 134.0.2 of FireFox......AND, I'm a good guy. I think so, anyway. What am I doing wrong. It seems that each time this happens, if and when the computer will restart, that FireFox has an update in the wings and needs to have that installed before I move on to use the pc. Is there a connection? Sid Hausding paid subscriber and fan of FireFox since your beginning
