This happened to me when I use chrome. He just opens the console and "Freezes." This is what worked for me.
Open the console. Go to the sources tab 
Then you check in the lower right corner of the breakpoint of the event listener. You will see a long list of DOM events, for example, click, keyboard, i.e. 
If any of the events is checked, clear the check box.
If this screen still appears, press F8 and then CTRL + F8. This fixes the problem. Hope this helps.
