Issues with by MBP (M1) are almost always memory related. The Activity Monitor is my friend to find out which processes are hogging precious memory across my seven virtual desktops.

My biggest win was with Firefox (with lots of windows and tabs open to allow quick context switching between projects) when I discovered the "Auto Tab Discard" extension which frees up memory for inactive tabs.

My Activity Monitor Memory Pressure is mostly green now.

you're right, Firefox is gobbling up about half of the RAM

thanks for pointing me in this direction
