I have a mac mini 10.9.5 and because I use it so often, I usually put it to sleep rather than shut it off. When I wake the computer and try to open Firefox from my dock, the page won't load - or it loads a blank page. I have to wait a couple of minutes or so until the "Icon wheel" stops spinning, then close it and reopen it. It works the second time, every time however. If I try to close it while the "icon wheel" is still spinning and reopen it it just does the same thing (won't open again) which just prolongs the frustration. So I HAVE to wait for the wheel to stop and then retry it every time. If a blank page comes up and I try to go to my GMail, then that page won't load until I reopen Firefox. Very frustrating! Any ideas? BTW I am not great with computers so I would appreciate very detailed instructions.

I came to the conclusion that a computer is like a person maybe. And that when you wake it up it takes a few minutes for it to get alert again.... Is that the case?
