When Firefox is the active window, hitting the media keys I've set on my mouse does nothing. They work perfectly fine if any other program is active, even if it's not the program the media keys are controlling. This doesn't seem to be a problem for any other keys, and when I use the media keys on my keyboard they work just fine. This had to have started just hours ago, I was changing volume without issue earlier today. I've already done the usual troubleshooting steps I can think of: -Flip every setting I can find that could have to do with media keys -Update/Reinstall relevant software -Turned it off and on again -Disabled extensions I've also tried some weird stuff that didn't work: -Changing the command in Logitech's gaming software from a media key to the keystrokes that activate that media key on the keyboard; it doesn't like that, it won't take those as inputs. I'm at a complete loss for how to fix this one. Running: Firefox 60.0.1, Logitech Gaming Software 9.00.42, Windows 10 64-bit
