I am working with Firefox with multiple tabs open, and 2 instances of Firefox on desktop. I close out of Firefox completely, and later when I want to bring it back up it will not load because there is an instance of it running already. That's when I go into the task manager and find at one or more instances running trhat I manually close out.
