Firefox hangs when I press XF86Calculator / XF86Mail (special Calculator/Mail buttons)
I have a few special buttons on my keyboard (Calculator / Mail). I've set them (on lxde-rc.xml) to run a simple bash script (Volume up / down using pactl). Unfortunately, I've noticed that only on Firefox hangs when I press these buttons (tested with terminal/slack/IDEs/Chrome, no issues). It's a ~2 seconds hang that prevents me from doing anything (tried scrolling/typing/clicking, nothing).
Any way to see what is actually happening / disable this behavior?
