Disable Firefox event log in console

As soon as I open Firefox console it starts printing every mouse move or click I do into console. I never enabled such feature, maybe I might have pressed some shortcut since this is a fresh install.
This starts on any website I visit. Even if I try with Private window same issue happens, even with all add-ons turned off.
F12 > Debugger > Untick LOG

Xcode: "Hide Navigator" ⌘, 0 stopped working. Why did it disappear?

In Xcode, there is a keyboard shortcut to hide the navigator, ⌘,0. But it stopped working. I went to system preferences and manually added it back but it disappeared again. Why does this keep happening?
I just realized that I had the developer documentation window open. For some reason, when this window is open, the "Hide Navigator" keyboard shortcut is no longer active. For all currently open Xcode windows. However, the command (⌘, 0) works only once to close the navigator in the developer documentation window then stops working until you close the window.

Mac keyboard shortcuts not working on iOS Simulator

All the mac keyboard short cuts like Cmd + Q (Quit Simulator app), Cmd + K (Toggle keyboard hide/show in Simulator) etc has stopped workings for iOS Simulator app since this morning suddenly.
All other apps, including Xcode, shows the shortcut in menus and they are working fine.
I noticed, the shortcut keys shows up against menu items momentarily on launch of simulator but then disappears completely (see attached)...
I tried following but no success...
Launch simulator (Open Xcode project and then menu Product > Run. And, directly through menu Xcode > Open Developer Tools).
Erase All Content and Settings in Simulator...
Restart Mac
Xcode 9.0.1 (9A1004) | Mac 10.13 (17A405)
You might have enabled (checked) the "Send all keyboard shortcuts to device" mode. It's in the Hardware > Keyboard submenu.
Pressing both Left and Right Cmd keys at the same time will exit keyboard capturing mode and re-enable menu shortcuts.
You might have disabled(unchecked) "Connect hardware keyboard" option which is in the hardware/keyboard menu. Make sure its checked.
You may need to press the esc key on newer versions of the simulator.
You can also choose which key stops shortcut capture.

Can I configure emacs to run a custom function when its dock icon is clicked?

I'm trying to set up Emacs as a daemon on Mac OS X. The major issue I'm running into is that if I close all the open frames, the remaining GUI elements (menu bar and dock icon) become nonfunctional for emacs until an new frame is opened by running emacsclient -c in a terminal. I don't know much about application programming in OS X, but I assume that when I click on the dock icon for Emacs, or launch it some other way while it is running, it triggers some sort of "activate" event. Is there any way for me to "catch" this event in elisp and run a custom function instead of the default behavior? (The custom function would create a new frame if Emacs is running as a daemon and no GUI frame is currently visible.)
For what it's worth, I came up with a workaround for this. Whenever the last GUI frame is closed and Emacs is not quitting, it creates a new hidden GUI frame. This makes sure that as long as Emacs is running, a GUI frame exists.
Edit: Now an Emacs package: https://github.com/DarwinAwardWinner/osx-pseudo-daemon
