Firefox keeps running after making a headless screenshot, can only kill it

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36 Steps to reproduce: ./firefox --window-size=1280,1024 -screenshot test.png mozilla.org *screenshot is made, waiting for firefox to quit, it never quits, so hitting control-c* ./firefox --window-size=1280,1024 -screenshot test.png mozilla.org *directly gives back control to the shell, due to invisible popup* Actual results: It makes a screenshot and then never quits. There is no way to quit firefox after making a screenshot except signals like killall/control-c. Killing it places firefox in a "closed unexpected" mode. While in this mode no screenshots are made given there is an (invisible) dialog that needs to be clicked away ("A copy of Firefox is already open. Only one copy of Firefox can be open at a time."). When the "unexpected" dialog is open, making a screenshot again results in being returned to my shell, while there is a firefox process that waits idle until someone clicks an invisible dialog. Using windowed mode the message can be clicked away. But it will re-appear due to needing to stop firefox. Expected results: Dialogs should never appear as there is no UI: dismiss all and make a screenshot in one of the following ways. A: Make a screenshot and then quit, let me wait until the screenshot is finished. This is by far the easiest for shell integration. Which was the goal here. B: Leave firefox open, but accept more commands (screenshot, quit) in some documented way from the command line. This requires some more tricky programming to control it programmatically.

Comment on attachment 8914817 [details] Bug 1403934 - Fix headless screenshot shutdown on MacOS. I am not sure this is a mainline scenario. Assuming this isn't, I'd prefer this fix ride the 58 train. Sorry!
