unwanted dev tools pop up

more options

Whenever i go to press the volume key (also the f12 key) on my macbook pro volume is disabled and a mozilla dev tools window opens. How can I disable this short cut? I tried going into keyboard short cuts and turning it off but the window keeps popping up.

Hi lakeofstew, are these hard buttons or TouchBar buttons?

I think most browsers use F12 to open developer tools, so that doesn't seem strange. But is Firefox ignoring the Fn key that changes F12 to a media key? Or maybe it's the other way around: Firefox thinks Fn is pressed when it's not?
