For some reason Firefox on my Void Linux machine now has the process name of GeckoMain. Okay, whatever. But on an almost daily basis I have to issue a command to kill it so it doesn't hang up my X session. So before I would just enter

pkill firefox

Someone had a bright idea to change this so now it is even more obscure. So now I have to type just a few extra characters:

pkill -f firefox

Silly, I know, but annoying as hell.
